Demote and extend 'TCP repair off' failure log.

The error in tcp_repair_off() is ignored, so log it as a warning. Include the file descriptor and error code in the debug message to make it more useful. Fixes: e7ba909 (2016-03-14 "cr-check: Inspect errno on syscall failures") Signed-off-by: Michał Mirosław <[email protected]>
