afr: misc performance improvements
1. In afr_getxattr_cbk, consider the errno value before blindly launching an inode refresh and a subsequent retry on other children. 2. We want to accuse small files only when we know for sure that there is no IO happening on that inode. Otherwise, the ia_sizes obtained in the post-inode-refresh replies may mismatch due to a race between inode-refresh and ongoing writes, causing spurious heal launches.
