[PATCH v6] nbd: well form nbd_iter_channel_error errp handler


From: Vladimir Sementsov-Ogievskiy
Subject: [PATCH v6] nbd: well form nbd_iter_channel_error errp handler
Date: Wed, 27 Nov 2019 22:08:40 +0300

Make nbd_iter_channel_error errp handler well formed:
rename local_err to errp_in, as it is IN-parameter here (which is
unusual for Error**).
