[SCSI] bfa: FC credit recovery and misc bug fixes.
- Introduce FC credit recovery.
- Added module parameter to enable/disable credit recovery.
Bug Fixes:
- Removed check for ignoring plogi from initiator in switched fabric mode.
- The ABTS for PLOGI is going out few millisecs earlier due to FW
timer calibration (around 300 miilisecs earlier). So there is a
window if an accept comes during this time HBA would have initiated
an ABORT.
- Added 1 to FC_ELS_TOV for compensating for FW timer.
