mm/damon/sysfs-schemes: handle tried region directory allocation failure
DAMON sysfs interface's before_damos_apply callback
(damon_sysfs_before_damos_apply()), which creates the DAMOS tried regions
for each DAMOS action applied region, is not handling the allocation
failure for the sysfs directory data. As a result, NULL pointer
derefeence is possible. Fix it by handling the case.
