[LTP] [PATCH] mem/tunable:min_free_kbytes: fix disabled check_monitor flag

[Gao Xiang]

From: Xiang Gao <gaoxiang@kylinos.cn>

In min_free_kbytes, check_monitor() is effectively disabled because
the loop condition uses the flag incorrectly.

Fix the condition so the monitor runs during the test and exits after
receiving the signal.
