Subject: [PATCH 5.9 021/105] ibmvnic: reduce wait for completion time

From: Dany Madden <drt@...ux.ibm.com>

[ Upstream commit 98c41f04a67abf5e7f7191d55d286e905d1430ef ]

Reduce the wait time for Command Response Queue response from 30 seconds
to 20 seconds, as recommended by VIOS and Power Hypervisor teams.

Fixes: bd0b672313941 ("ibmvnic: Move login and queue negotiation into ibmvnic_open")
Fixes: 53da09e92910f ("ibmvnic: Add set_link_state routine for setting adapter link state")
