[PATCH 05/12] mm/damon/sysfs: remove probes number validation

[SJ Park]

DAMON sysfs interface is disallowing >DAMON_MAX_PROBES nr_probes input,
since DAMON_MAX_PROBES is the upper limit of probes per DAMON context.
The core layer is validating the upper limit again, though.  It is
preferred to let DAMON API callers such as sysfs interface to set
parameters in flexible ways, and do parameters validation in the core
layer.  Drop the duplicated validation in the sysfs interface.
