afr: Consider ENOSPC and EDQUOT as symmetric errors
Problem:
Since commit 8eaa3506ead4f11b81b146a9e56575c79f3aad7b, in replica 3, if a
brick is down and a create fails on the other 2 brick with EDQUOT, we consider
it an unsymmetric error and hence do not do post-op. So the dirty xattr
remains set on the parent dir, leading to conservative merges during heal when
all bricks are up. i.e. a file deleted on the source might re-appear after heal.
Fix:
Consider ENOSPC and EDQUOT as symmetric errors since there is no
possibility of partial inode or entry modification operations possible when
quota is enabled. IOW, if quota reports EDQUOT, the no. of bytes written
(or not written) will be the same on all bricks of the replica.
Likewise, the entry operation (create, mkdir...) will either succeed or
not succeed on all bricks.
