RDMA/rxe: Remove useless code in rxe_recv.c

Browse Source 
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.
