[PATCH 2/2] hwclock: fix debug regression

[J William Piggott <elseifthen@gmx.com>]

commit f0a0ce7 makes debug mode implicit for the --test option.

Using the previous command syntax of --test and --debug
together invokes the undocumented Level 2 debugging when
setting the RTC. This can cause many thousands of lines of
output like:
1510967983.499968 < 1510967983.500000 (-0.000032)

Fix: bump Level 2 debugging to Level 9, just before the
other undocumented Level 10. This makes it improbable for
the development debug levels to be accessed unintentionally.
