Lv Zheng 9b019b0f67 ACPICA: Tables: Cleanup table handler invokers
ACPICA commit 4551f51fa8ba33a977721c3b250cb70a309e3f23

Recently, we allows the table mutex to be held in both early and late stage
APIs. This patch further cleans up the related code to reduce redundant
code related to acpi_gbl_table_handler. Lv Zheng.
