[PATCH][next] RDMA: fix allocation failure on pointer pd

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The null check on an allocation failure on pd is currently checking
if pd is non-null rather than null. Fix this by adding the missing !
operator.

Fixes: 21a428a019c9 ("RDMA: Handle PD allocations by IB/core")
