Dan Carpenter f3c70430d8 xprtrdma: checking for NULL instead of IS_ERR()
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')
