wifi: rtw88: fix incorrect error codes in rtw_debugfs_copy_from_user
If there is a failure during copy_from_user or user-provided data
buffer is invalid, rtw_debugfs_copy_from_user should return negative
error code instead of a positive value count.
Fix this bug by returning correct error code. Moreover, the check
of buffer against null is removed since it will be handled by
copy_from_user.
