Amery Hung ea5ab23898 bpf: Classify kfunc mem_size args from BTF without register state ...

check_kfunc_args() already makes sure a scalar value is passed to a
scalar kfunc argument. Drop the check in is_kfunc_arg_mem_size() and
is_kfunc_arg_const_mem_size() to further decouple
get_kfunc_ptr_arg_type() from register state (a prerequisite for
generating a helper-like prototype from kfunc's BTF).
