[SCSI] libfcoe: formatting and comment cleanups 

Ensures that there are kernel-doc style comments for all
routines and structures.

There were also a few instances of fc_lport's named 'lp'
which were switched to 'lport' as per the libfc/libfcoe/fcoe
naming convention.

Also, emacs 'indent-region' and 'tabify' were ran on libfcoe.c.
