mei: vsc: Unregister interrupt handler for system suspend
Unregister the MEI VSC interrupt handler before system suspend and
re-register it at system resume time. This mirrors implementation of other
MEI devices.
This patch fixes the bug that causes continuous stream of MEI VSC errors
after system resume.
Fixes: 386a766c4169 ("mei: Add MEI hardware support for IVSC device")
