Subject: xprtrdma: checking for NULL instead of IS_ERR()
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit abfb689711aaebd14d893236c6ea4bcdfb61e74c upstream.
The rpcrdma_create_req() function returns error pointers or success. It
never returns NULL.
Fixes: f531a5dbc451 ('xprtrdma: Pre-allocate backward rpc_rqst and send/receive buffers')
