locking/qspinlock: Rename mcs lock/unlock macros and make them more generic

maillist inclusion
category: feature
bugzilla: 169576
CVE: NA

Reference: https://lore.kernel.org/patchwork/patch/1406513/



-------------------------------------------------

The mcs unlock macro (arch_mcs_lock_handoff) should accept the value to be
stored into the lock argument as another argument. This allows using the
same macro in cases where the value to be stored when passing the lock is
different from 1.
