There is nothing scsi specific about the ibmvfc_scsi_channels struct. It is meant to encapsulate a set of channels regardless of protocol.
Remove _scsi from the struct name to reflect this genric nature.

scsi: ibmvfc: Fix erroneous use of rtas_busy_delay with hcall return code

scsi: ibmvfc: Fix erroneous use of rtas_busy_delay with hcall return code
Commit 0217a272fe13 ("scsi: ibmvfc: Store return code of H_FREE_SUB_CRQ during cleanup") wrongly changed the busy loop check to use rtas_busy_delay() instead of H_BUSY and H_IS_LONG_BUSY(). The busy return codes for RTAS and hypercalls are not the same.
Fix this issue by restoring the use of H_BUSY and H_IS_LONG_BUSY().

scsi: ibmvfc: Implement channel queue depth and event buffer accounting
Extend ibmvfc_queue, ibmvfc_event, and ibmvfc_event_pool to provide queue depths for general I/O commands and reserved commands as well as proper accounting of the free events of each type from the general event pool. Further, calculate the negotiated max command limit with the VIOS at NPIV login time as a function of the number of queues times their total queue depth (general and reserved depths combined).
This does away with the legacy max_request value, and allows the driver to better manage and track it resources.

scsi: ibmvfc: Remove BUG_ON in the case of an empty event pool
In practice the driver should never send more commands than are allocated to a queue's event pool. In the unlikely event that this happens, the code asserts a BUG_ON, and in the case that the kernel is not configured to crash on panic returns a junk event pointer from the empty event list causing things to spiral from there. This BUG_ON is a historical artifact of the ibmvfc driver first being upstreamed, and it is well known now that the use of BUG_ON is bad practice except in the most unrecoverable scenario. There is nothing about this scenario that prevents the driver from recovering and carrying on.
Remove the BUG_ON in question from ibmvfc_get_event() and return a NULL pointer in the case of an empty event pool. Update all call sites to ibmvfc_get_event() to check for a NULL pointer and perfrom the appropriate failure or recovery action.
