[PATCH v2] SCSI: fcoe: convert to use BUS_ATTR_WO

We are trying to get rid of BUS_ATTR() and the usage of that in the fcoe
driver can be trivially converted to use BUS_ATTR_WO(), so use that
instead.

v2: Made simpler with wrapper functions to call the "real" show/store
functions, thanks to James for the idea.
Removed the EXPORT_SYMBOL() removal line, that belongs in a separate
patch
