scsi: fnic: Make debug logging protocol independent

Browse source 
Make the fnic debug macros take struct fnic instead of struct Scsi_Host so
FCP and NVMe initiator roles can share the same logging interface.

Add fnic_printk() to route FCP initiator messages through shost_printk()
and non-SCSI role messages through printk(). Add role and non-SCSI role
messages through printk(). Add role predicates and separate FDLS, FIP, and
NVMe logging masks.

Convert FCS, FIP, SCSI, ISR, and main debug call sites to pass the fnic
instance directly, and keep FIP VLAN MAC descriptors skipped while
reporting unexpected descriptor types.
