cluster/ec: Do not start heal on good file while IO is going on

Problem:
Write on a file has been slowed down significantly after
http://review.gluster.org/#/c/13733/

RC : When update fop starts on a file, it sets dirty flag at
the start and remove it at the end which make an index entry
in indices/xattrop. During IO, SHD scans this and finds out
an index and starts heal even if all the fragments are healthy
and up tp date. This heal takes inodelk for different types of
heal. If the IO is for long time this will happen in every 60 seconds.
Due to this extra, unneccessary locking, IO gets slowed down.

Solution:
Before starting  any  type of heal check if file needs heal or not.
