Gustavo A. R. Silva 7a55a5159d scsi: fcoe: Fix Wstringop-overflow warnings in fcoe_wwn_from_mac()
[ Upstream commit 54db804d5d7d36709d1ce70bde3b9a6c61b290b6 ]

Fix the following Wstringop-overflow warnings when building with GCC-11:

by changing the array size to the correct value of ETH_ALEN in the
argument declaration.

Also, fix a couple of checkpatch warnings:
WARNING: function definition argument 'unsigned int' should also have an identifier name

This helps with the ongoing efforts to globally enable
-Wstringop-overflow.
