ext4: don't report EOPNOTSUPP errors from discard

Browse source

When ext4 is mounted without journal, with discard mount option, and on
a device not supporting trim, we print error for each and every freed
extent. This is not only useless but actively harmful. Instead ignore
the EOPNOTSUPP error. Trim is only advisory anyway and when the
filesystem has journal we silently ignore trim error as well.
