Fix delaying requests to unknown virtual ports 2s after init.

This code was originally implemented 7 years ago, but never really worked
due to trivial error. I think this functionality may be not required.
Initiators supporting optional periodic command status checks detected
those terminated commands and retried them 3 seconds later. But thinking
about less featured initiators and the fact that it is our race makes
virtual ports "unknown" it may be good to have this feature.

Simplify memory allocation for NS requests.

Since we no longer need additional buffers for request and response IOCBs,
we can increase receive space by 192 bytes, that is enough for fetching 48
more ports. The new limit is 1020 fabric ports per virtual port.

For some reason firmware sends Port Database Changed notifications in case
of explicit login requests from the driver when target port is unavailabe.
Those notifications don't give driver any new information, but only cause
infinite scan loop.

Make all CT Pass-Through (name server requests) asynchronous.

Previously we had to do it synchronously because we could not drop the lock
due to potential scratch memory use conflicts. Previous commits fixed that
collision, so here it goes -- slower and less reliable external requests
are executed asynchronously without spinning in tight loop and with more
safe timeout handling.

Switch isp_getpdb() to synchronous IOCB DMA area.

While technically it is not IOCB, it is synchronous and can be called from
different places, so calling FC_SCRATCH_ACQUIRE() here is inconvenient.

Allocate separate DMA area for synchronous IOCB execution.

Usually IOCBs should be put on queue for asynchronous processing and should
not require additional DMA memory. But there are some cases like aborts and
resets that for external reasons has to be synchronous. Give those cases
separate 2*64 byte DMA area to decouple them from other DMA scratch area
users, using it for asynchronous requests.
