cluster/afr : Fix self-heal of special files
Fixes self-heal of special files like device files, fifo files, socket files etc. Does it by doing the following: * Prevent setting of pending data xattr on a special file during entry self-heal when a new fils is created. * Allow data self-heal to be started on all file types other than directories. During data self-heal, for special files just erase pending xattrs, if those xattrs were set by previous releases of glusterfs.
