locking: Factor out queued_spin_release()
The contended_release tracepoint needs to hook queued_spin_unlock(), but
architectures with a custom unlock define queued_spin_unlock() directly,
leaving no single generic place to add the tracing.
Introduce queued_spin_release() as the arch-overridable release
primitive and make queued_spin_unlock() a generic wrapper around it.
An architecture that only customizes the release can then override
queued_spin_release() and inherit the generic wrapper.
Rename the MIPS override to queued_spin_release() accordingly. x86
paravirt overrides queued_spin_unlock() directly and is left unchanged.
No functional change intended.
