[lustre-devel] [PATCH 19/25] lustre: lnd: Don't Assert On Reconnect with MultiQP

[James Simmons <jsimmons@infradead.org>]

From: Doug Oucharek <dougso@me.com>

The work from LU-8943 activated the ability to have multiple
connections between peers. If any of those connections need to be
reconnected (i.e. parameter renegotiation), we were getting
an assert from kiblnd_reconnect_peer() which was not changed
to allow for having multiple connections ongoing at the
same time.

This patch gets rid of the assert from kiblnd_reconnect_peer()
which is no longer valid after LU-8943.
