mtime not being preserved in replicate self-heal

[Brent A Nelson <brent@xxxxxxxxxxxx>]

I just did a trace, where self-heal was triggered and destroyed the mtime 
on the second half of the mirror (this was a directory that was created by 
kernel-nfs reexport, so the files were created "dirty").  It appears that 
metadata self-heal never actually occurs in this scenario, only data 
self-heal.  Further, after the mtime is destroyed on the second half of 
the mirror, self-heal never seems to notice that the mtimes are different 
and never fixes it.
