RDMA/rxe: For invalidate compare according to set keys in mr
[ Upstream commit 174e7b137042f19b5ce88beb4fc0ff4ec6b0c72a ]
The 'rkey' input can be an lkey or rkey, and in rxe the lkey or rkey have
the same value, including the variant bits.
So, if mr->rkey is set, compare the invalidate key with it, otherwise
compare with the mr->lkey.
Since we already did a lookup on the non-varient bits to get this far, the
check's only purpose is to confirm that the wqe has the correct variant
bits.
