Subject: RDMA/ocrdma: Fix error codes in ocrdma_create_srq()
Patch-mainline: v4.13-rc2
Git-commit: f0c6e88288d65c93bbc7da4fb6f7d51b2733228a
References: bsc#1058513 FATE#322520
If either of these allocations fail then we return ERR_PTR(0). That's
equivalent to NULL and results in a NULL pointer dereference in the
caller.
Fixes: fe2caefcdf58 ("RDMA/ocrdma: Add driver for Emulex OneConnect IBoE RDMA adapter")
