[PATCH 027/379][SRU][OEM-5.6] net: qrtr: Fix error pointer vs NULL bugs

[You-Sheng Yang]

From: Dan Carpenter <dan.carpenter at oracle.com>

BugLink: https://bugs.launchpad.net/bugs/1879633

The callers only expect NULL pointers, so returning an error pointer
will lead to an Oops.

Fixes: 0c2204a4ad71 ("net: qrtr: Migrate nameservice to kernel from userspace")
