From: Wei Yongjun <weiyongjun1@huawei.com>

[ Upstream commit 39f2495618c5e980d2873ea3f2d1877dd253e07a ]

Fix to return a negative error code from the mthca_cmd_init() error
handling case instead of 0, as done elsewhere in this function.

Fixes: 80fd8238734c ("[PATCH] IB/mthca: Encapsulate command interface init")
