mm/damon/sysfs: remove parameters of damon_sysfs_region_alloc()
'damon_sysfs_region_alloc()' is always called with zero-filled 'struct
damon_addr_range', because the start and end addresses should set by
users. Remove unnecessary parameters of the function and simplify the
body by using 'kzalloc()'.
