RDMA/rxe: Remove useless code in rxe_recv.c
In check_keys() in rxe_recv.c
if ((...) && pkt->mask) {
...
}
always has pkt->mask non zero since in rxe_udp_encap_recv() pkt->mask is
always set to RXE_GRH_MASK (!= 0). There is no obvious reason for this
additional test and the original intent is lost. This patch simplifies the
expression.
