ACPICA: Tables: Fix unbalanced table validations.

Browse source 
As acpi_tb_validate_table() returns failure on checksum verification without
doing invalidatation, all its invocations that are not done to a descriptor
stored in acpi_gbl_root_table_list are checked and balanced.

But this is not a real issue as the descritors that have been passed to
acpi_tb_add_table() are all virtual address tables and the validations are in
fact no-op.  The cleanup can ensure that any future extensions made on
acpi_tb_add_table() to allow it to be invoked with physical address tables
will not trigger memory leakage regressions.
