bnx2x: Changes with storage & MAC macros

Rearrange macros to query for storage-only modes in different MF environment.
Improves the readibility and maintainability of the code. E.g.:
	-	if (IS_MF_STORAGE_SD(bp) || IS_MF_FCOE_AFEX(bp))
	+	if (IS_MF_STORAGE_ONLY(bp))

In addition, this removes the need for bnx2x_is_valid_ether_addr().
