Subject: [PATCH 1/1] infiniband: hw: ocrdma: fix bad initialization

From: Pan Bian <bianpan2016@....com>

In function ocrdma_mbx_create_ah_tbl(), returns the value of status on
errors. However, because status is initialized with 0, 0 will be
returned even if on error paths. This patch initialize status with
"-ENOMEM".
