RDMA/rxe,siw: Restore uverbs_cmd_mask IB_USER_VERBS_CMD_POST_SEND

These two drivers open code the call to POST_SEND and do not use the
rdma-core wrapper to do it, thus their usages was missed during the audit.

Both drivers use this as a doorbell to signal the kernel to start DMA.

Fixes: 628c02bf38 ("RDMA: Remove uverbs cmds from drivers that don't use them")
