cluster/afr: Add quorum checks to open & opendir fops
Problem:
Currently even if open & opendir fails on quorum number of bricks,
but succeeds on atleast one brick, it will result in success. This leads
to inconsistency in the behaviour with other operations following the
open, which has quorum checks.
Fix:
Add quorum checks to open & opendir fops to avoid inconsistency.
