- What I did
Don't stop sxdkernel during warm shutdown on Mellanox platform since it may take 15-20 sec to stop

- How I did it
Place sxdkernel stop under if [[ x"$WARM_BOOT" != x"warm" ]] statement

- How to verify it
Run warm reboot 100 times with and without this change:
Without this change: 1 of 10 runs LAG on neighbor may go down
With this change: After 100 reboots LAG never went down

- Description for the changelog

@stepanblyschak does Mellanox platform support fast reboot at all? Your change effectively stopped module removal if the reboot type is fast reboot. If you plan to support fast reboot on Mellanox platform. This is a change you didn't mention in your test section.

@yxieca Fast reboot is supported on mellanox. In case of fast reboot WARM_BOOT variable is false so it still stops the module - this is how it was before the change, so I don't understand how this change affects fast reboot

@stepanblyschak oh my bad. I was looking at change in the mindset of warm-reboot script. The comments explains all and your test is sufficient.
