Serio ports are not being restarted any longer because resume operations
after hibernate do nothing, since the device has not been marked as
suspended. This happens because suspend is only considering the SUSPEND
event but not the FREEZE event.

Note that this driver has still to migrate to dev_pm_ops, but this fixes
this particular bug now.

Current implementation of spin_event_timeout can be interrupted by an
IRQ or context switch after testing the condition, but before checking
the timeout.  This can cause the loop to report a timeout when the
condition actually became true in the middle.

This patch adds one final check of the condition upon exit of the loop
if the last test of the condition was still false.
