Revert "ACPICA: Namespace: Fix deadlock triggered by MLC support in dynamic table loading" 



Revert commit 2f38b1b1 (ACPICA: Namespace: Fix deadlock triggered by
MLC support in dynamic table loading) that attempted to fix a deadlock
issue introduced by a previous commit, but it led to a lock ordering
inconsistency that caused further problems to appear.
