ACPI: OSL: Add missing __acquires/__releases annotations
Sparse reports a warnings at acpi_os_acquire_lock() and
acpi_os_release_lock():
warning: context imbalance in acpi_os_acquire_lock() - unexpected unlock
warning: context imbalance in acpi_os_release_lock() - unexpected unlock
which result from missing __acquires/__releases annotations.
Add the annotations as appropriate to get rid of the warnings.
