Revert "ACPICA: Namespace: Fix deadlock triggered by MLC support in dynamic table loading"
Revert commit 2f38b1b16d92 (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.
Fixes: 2f38b1b16d92 (ACPICA: Namespace: Fix deadlock triggered by MLC support in dynamic table loading)
