[lustre-devel] [PATCH 19/24] lnet: Check for -ESHUTDOWN in lnet_parse

From: Chris Horn <chris.horn at hpe.com>

The fix for LU-8106, http://review.whamcloud.com/19993, no longer
works because rc does not have the return value from
lnet_nid2peerni_locked(). Use PTR_ERR to get the return value and
restore the LU-8106 fix.

HPE-bug-id: LUS-10333
Fixes: 6e872a4ffd ("lustre: lnet: peer/peer_ni handling adjustments")
WC-bug-id: https://jira.whamcloud.com/browse/LU-14962
