features/index: Ignore regular files when examining state of the inode wrt ENTRY_CHANGES

	Backport of: http://review.gluster.org/14870

This prevents unnecessary sys_lstat() syscall when xattrop
is operating on regular files.

Also, to avoid (even) the one-time execution of sys_lstat()
syscalls on disperse volumes or replicate volumes when granular
entry self-heal is disabled, we pass a key in afr_selfheal_undo_pending()
indicating to index that this xattrop is on a granular directory index.
Index will accordingly decide whether or not to attempt the index state
initialization.
