[SCSI] bfa: IOC bug fixes.

- Add logic to handle the case where PCI mapping goes away when
  IOCPF state machine is waiting for semaphore.
- Added logic to unlock hw semaphore if the previos FW boot was
  from flash based and the current FW initialization attempt is from OS.
- Added fix to update hbfails and hb_count stats during hwerror event.
