The ACPI 4.0 specification has been changed to make the SyncLevel
for mutex objects more useful. When releasing a mutex, the
synclevel of the mutex must now be the same as the current sync
level. This makes more sense. This change updates the code to
match the spec.

Fixes a problem where if multiple mutexes of the same sync level
are acquired but then not released in strict opposite order, the
current sync level becomes confused and can cause errors.

Warnings can be generated for printf-like statements that output
the ACPI_THREAD_ID on 64-bit builds, since this type can expand
to 64-bits depending on how it is defined. Use the %p format
specifier to allow the output to automatically expand to 64 bits.
