SQ params from userspace are checked in by set_user_sq_size(). But
when the check fails, the function doesn't return but instead keep
running and overwrite 'ret'. As a result, the invalid params will
not get blocked actually.
Add a return right after the failed check. Besides, although the
check result of kernel sq params will not be overwritten, to keep
coding style unified, move default_congest_type() before
set_kernel_sq_size().
