ACPICA: Events: Always modify GPE registers under the GPE lock
It is reported that there are pieces of code invoking acpi_ev_finish_gpe()
without holding acpi_gbl_gpe_lock. Since this function will modify GPE
register values, there could be races breaking the register modification
process.
This patch fixes this issue. Lv Zheng.
