Subject: [PATCH] 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]
