Add link related log messages in fnic_fcs.c,
Improve log message in fnic_fcs.c,
Add log message in vnic_dev.c.
Changes between v2 and v3:
Incorporate review comment from Hannes:
Modify FNIC_MAIN_DBG to prepend fnic number.
Modify FNIC_MAIN_DBG definition to prepend function name
and line number.
Modify FNIC_FCS_DBG definition to prepend function name
and line number.
Replace FNIC_MAIN_DBG with FNIC_FCS_DBG in fnic_fcs.c
Use fnic_num as an argument to FNIC_MAIN_DBG and FNIC_FCS_DBG.
Host number is still used as an argument to
FNIC_MAIN_DBG and FNIC_FCS_DBG since it in turn
uses shost_printk.
