ACPI: EC: PM: Flush EC work unconditionally after wakeup
Commit 607b9df63057 ("ACPI: EC: PM: Avoid flushing EC work when EC
GPE is inactive") has been reported to cause some power button wakeup
events to be missed on some systems, so modify acpi_ec_dispatch_gpe()
to call acpi_ec_flush_work() unconditionally to effectively reverse
the changes made by that commit.
Also note that the problem which prompted commit 607b9df63057 is not
reproducible any more on the affected machine.
