mm/damon/core: initialize ->esz_bp from damos_quota_init_priv()

Patch series "mm/damon: misc fixes and improvements".

Add miscelleneous and non-urgent fixes and improvements for DAMON code,
selftests, and documents.


This patch (of 10):

damos_quota_init_priv() function should initialize all private fields of
struct damos_quota.  However, it is not initializing ->esz_bp field.  This
could result in use of uninitialized variable from
damon_feed_loop_next_input() function.  There is no such issue at the
moment because every caller of the function is passing damos_quota object
that already having the field zero value.  But we cannot guarantee the
future, and the function is not doing what it is promising.  A bug is a
bug.  This fix is for preventing possible future issues.
