Jie Liu 19e8ac2721 ocfs2: return EOPNOTSUPP if the device does not support discard 
For FITRIM ioctl(2), we should return EOPNOTSUPP to inform the user that
the storage device does not support discard if it is, otherwise return
success would confuse the user even though there is no free blocks were
trimmed at all.
