DAMOS quota goals commit unit test is mistakenly not testing a test case that was designed to test. DAMOS quota goals and DAMON sysfs refresh_ms file have bugs that can produce non critical but still unexpected behaviors. Fix the bugs. Patch 1 fixes the DAMOS quota goals commit unit test to cover a mistakenly uncovered case. Patches 2 and 3 fix the bugs in DAMOS PSI goal initialization and eligible_mem_bp online commit, respectively. Patch 4 fixes the bug in DAMON sysfs refresh_ms file handling. This patch (of 4): damon_test_commit_quota_goal_for() is set to test committing a new psi goal on an existing psi goal. However, damon_test_commit_quota_goal() is mistakenly not covering the test case. Add the test case.
