cluster/afr: Fix witness counting code in src/sink detection
Problem:
In afr-v1 pre-op, xattrop increments self xattr first then it increments the
value on rest. In post-op, xattr value is decreased first on rest and at last
it gets decremented on self. So for a possible operation to be witnessed i.e.
a fop is seen by the brick it is important to have at least 1 pending op
because without completing pre-op fop won't come. The other possibility is when
fop completes but at the time of post-op after decrementing pending counts on
others just before decrementing its own pending count, the brick dies.
Fix:
Fix witness detection code in afr_self_heal_find_direction()
BUG: 1322253
