Improve existing logs by adding fnic number, hardware queue,
tag, and mqtag in the prints.
Add logs with the above elements for effective debugging.

Changes between v4 and v5:
Incorporate review comments from Martin:
Modify patch commits to include a "---" separator.
Changes between v2 and v3:
Incorporate the following review comment from Hannes:
Use fnic_num as an argument to FNIC_SCSI_DBG.
Modify definition of FNIC_SCSI_DBG.
Host number is still an argument since
FNIC_SCSI_DBG in turn uses shost_printk.
