scsi: fcoe: Remove redundant assignment to variable 'wlen'

Variable wlen is being assigned a value that is never read, it is being
re-assigned with a different value later on. The assignment is redundant
and can be removed.

Cleans up clang scan build warning:
drivers/scsi/fcoe/fcoe.c:1491:2: warning: Value stored to 'wlen'
is never read [deadcode.DeadStores]
