From: Pan Bian <bianpan2...@163.com> When the calls to mempool_create_slab_pool() return unexpected values, the value of return variable err is 0. 0 means no error. Thus, the caller of fnic_probe() cannot detect the error, and may be misled. This patch fixes the bug, assigning "-ENOMEM" to err before calling mempool_create_slab_pool().
