mm/damon/sysfs-schemes: handle tried regions sysfs directory allocation failure
DAMOS tried regions sysfs directory allocation function
(damon_sysfs_scheme_regions_alloc()) is not handling the memory allocation
failure. In the case, the code will dereference NULL pointer. Handle the
failure to avoid such invalid access.
