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().
