ACPICA: Fix code divergence of global lock handling
Commit 9cd0314(ACPI / ACPICA: Fix global lock acquisition) was backported
into ACPICA code base, and some divergence was introduced.
This patch fixed it,
- rename acpi_ev_global_lock_pending/acpi_ev_global_lock_pending_lock
to acpi_gbl_global_lock_pending/acpi_gbl_global_lock_pending_lock.
- move the initialization of acpi_gbl_global_lock_pending_lock from
acpi_ut_mutex_initialize to acpi_ev_init_global_lock_handler.
