Subject: [PATCH 23/30] ACPI: OSL: Add missing annotation for acpi_os_release_lock()

Sparse reports a warning at acpi_os_release_lock()

warning: context imbalance in acpi_os_release_lock() - unexpected unlock

The root cause is the missing annotation at acpi_os_release_lock()
Add the missing annotation __releases(lockp)
