Subject: [PATCH] scsi: fcoe: remove redundant call to skb_transport_header

From: Colin Ian King <colin.king@...onical.com>

Pointer fh is being assigned a return value from the call to
skb_transport_header however this value is never read and fh
is being re-assigned immediately afterwards with a new value.
Since there are side-effects from calling skb_transport_header
the call is redundant and can be removed.

Addresses-Coverity: ("Unused value")
