rapidio/rio_mport_cdev: use array_size() helper in copy_{from,to}_user()
Use array_size() helper instead of the open-coded version in copy_{from,to}_user(). These sorts of multiplication factors need to be wrapped in array_size(). This issue was found with the help of Coccinelle and, audited and fixed manually. Signed-off-by: Gustavo A. R.
