[PATCH 3/3] futex: Add missing annotation for fixup_pi_state_owner()

[Jules Irenge]

Sparse reports a warning at fixup_pi_state_owner()

warning: context imbalance in fixup_pi_state_owner() - unexpected unlock

The root cause is a missing annotation of fixup_pi_state_owner().

Add the missing __must_hold(q->lock_ptr) annotation
