Description

While adapting LU-234 to our branch I've found that ost_lock_put() is not called in some error cases. LU-234 added even more such cases. Please check patch attached. I have the question there - do we need to report repbody in case of error in ost_punch()? I doubt that but it is always returned there no matter is 'rc' zero or not.
