cluster/afr: Fix partial heals in 3-way replication
Problem:
When there are 2 sources and one sink and if two self-heal daemons
try to acquire locks at the same time, there is a chance that it
gets a lock on one source and sink leading partial to heal. This will
need one more heal from the remaining source to sink for the complete
self-heal. This is not optimal.
Fix:
Upgrade non-blocking locks to blocking lock on all the subvolumes, if
the number of locks acquired is majority and there were eagains.
BUG: 1318751
