[PATCH -next] ibmvnic: fix error return code in ibmvnic_probe()

[Wei Yongjun]

From: Wei Yongjun <weiyongjun1 at huawei.com>

Fix to return error code -ENOMEM from the dma_map_single error
handling case instead of 0, as done elsewhere in this function.

Fixes: 032c5e82847a ("Driver for IBM System i/p VNIC protocol")
