net/ixgbe: remove redundant MAC flag check

The flag of RTE_ETHTYPE_FLAGS_MAC has been checked twice, so remove the
first error message "Not supported by ethertype filter" which is not so
specific, and keep the error message "mac compare is unsupported" which
aligns to the definition of RTE_ETHTYPE_FLAGS_MAC.
