Revert "ACPICA: fix AML mutex re-entrancy"

This reverts commit c0d127b56937c3e72c2b1819161d2f6718eee877.

These changes to AML locking were made to allow
Notify handlers to be called on the stack
and not deadlock.  However, that scheme turns
out to be flawed and was reverted by the previous commit,
so this commit restores the locking to it previous design.
