[PATCH 7/8] selftests/damon/sysfs: hide expected write failures

[SeongJae Park]

DAMON selftests for sysfs (sysfs.sh) tests if some writes to DAMON sysfs
interface files fails as expected.  It makes the test results noisy with
the failure error message because it tests a number of such failures.
Redirect the expected failure error messages to /dev/null to make the
results clean.
