4.14-stable review patch.  If anyone has any objections, please let me know.


From: Moshe Shemesh <mo...@mellanox.com>

[ Upstream commit a2fba188fd5eadd6061bef4f2f2577a43231ebf3 ]

During unload, on mlx5_stop_eqs we move command interface from events
mode to polling mode, but if command interface EQ destroy fail we move
back to events mode.
That's wrong since even if we fail to destroy command interface EQ, we
do release its irq, so no interrupts will be received.
