Subject: net: qrtr: fix error return code of qrtr_sendmsg()
From: Jia-Ju Bai <baijiaju1990@xxxxxxxxx>
commit 179d0ba0c454057a65929c46af0d6ad986754781 upstream.
When sock_alloc_send_skb() returns NULL to skb, no error return code of
qrtr_sendmsg() is assigned.
To fix this bug, rc is assigned with -ENOMEM in this case.
