[PATCH rdma-next 2/4] IB/core: Remove unnecessary check in ibnl_rcv_msg

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Mark Bloch <markb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

RDMA_NL_GET_OP is defined like this: (type & ((1 << 10) - 1))
which means op (defined as an int) can never be a negative number.

Fixes: b2cbae2c2487 ('RDMA: Add netlink infrastructure')
