sc_cmd->sense_buffer is not guaranteed to be allocated so we need to
sc_cmd->check
if the pointer is NULL before trying to copy anything into it.
Fixes the crash:

If an fcport is not offloaded then the members of the qedf_rport struct
are undefined which may cause a system crash.

This patch advances the qed* drivers into using the newer firmware -
This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.
It also introduces a major 4-Cached SGE change in firmware, which can be
seen in the storage drivers' changes.
In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].

Based on an original patch by Hannes Reinecke.
The driver didn't follow the atomic_t vs refcount_t change, and anyway
one should be using kref_read() instead of accessing the counter inside
an kref.

- PCI driver registration
- libfc/fcoe host level initialization
- SCSI host template initialization and callbacks
- Debugfs and log level infrastructure
- Link handling
- Firmware interface structures
- QED core module initialization
- Light L2 interface callbacks
- I/O request initialization
- Firmware I/O completion handling
- Firmware ELS request/response handling
- FIP request/response handled by the driver itself
