sched/membarrier: Fix private expedited registration check
[ Upstream commit fc0d77387cb5ae883fd774fc559e056a8dde024c ]
Fix a logic flaw in the way membarrier_register_private_expedited()
handles ready state checks for private expedited sync core and private
expedited registrations.
If a private expedited membarrier registration is first performed, and
then a private expedited sync_core registration is performed, the ready
state check will skip the second registration when it really should not.
