nvmf: Add a transport hook to limit the maximum command capsule size
NVMe controllers advertise the largest supported size of a command
capsule in the controller data (IOCCSZ). Smart NIC offload transports
may have a cap on the size of the largest data PDU that can be
received. These transports can implement this hook to limit the
advertised IOCCSZ to limit the in-capsule-data payload sent by remote
hosts.

nvmf: Track SQ flow control
This isn't really needed since the host driver never submits more
commands to a queue than it can hold, but I noticed that the
recently-added SQ head and tail sysctl nodes were not updating. This
fixes that and also uses these values to assert that there we never
submit a command while a queue pair is full.
