[RFC PATCH 2/3] Revert "mm/damon/lru_sort: error out for >10000 active_mem_bp"

[SJ Park <sj@kernel.org>]

This reverts commit 06befa61c427e74319781e6f35a364cfc32dbae8.

The commit was made to avoid zero damos quota goal target value, because
it can trigger division-by-zero.  Now the core layer handles the corner
case.  It returns an error for any attempt setting the aero
target_value.  The corner case handling in DAMON_LRU_SORT is hence no
more needed.  Remove it.

Note that this slightly changes the user behavior.  It still disallows
active_mem_bp of 10,002.  But now it allows other >10,000 active_mem_bp
values. Setting >10,000 active_mem_bp makes not much sense.  But it
doesn't cause critical problems such as memory leak or crash, either.
Arguably that doesn't deserve additional code complexity.  Just allow
it.
