cluster/afr: Don't stop entry/data self-heal on metadata split-brain

Problem:
Entry/Data self-heal is orthogonal to meta-data self-heal.
meta-data split-brain should not affect entry/data self-heal.

Fix:
Prevented aborting rest of the self-heals when metadata split-brain
happens.

Tests:
1) Simulated meta-data split-brain then checked data-self-heal
succeed on regular file, entry-self-heal succeed on dir.
2) Reset meta-data change-log on one of the subvols and checked
that meta-data self-heal also completes.
3) Executed self-heal sanity script.
