Fix inc/dec_mnt_count for -rt
With Nick's vfs patches, inc/dec_mnt_count use per-cpu counters, so
this patch makes sure we disable preemption before calling.
Its not a great fix, but works because count_mnt_count() sums all the
percpu values, so each one individually doesn't need to be 0'ed out.
I suspect the better fix for -rt is to revert the mnt_count back to an atomic
counter.
