* fix potential lock up with M190 override
It's common to have a slicer configured to send "M190 S0" before PRINT_START (to discourage the slicer from inserting it's own M190.) Klipper's handling of "M190 S0" is to ignore the command instead of waiting for the bed to cool to a temperature it likely will never reach. This change fixes the bedfans.cfg version of M190 to also ignore a S0 parameter (and doesn't freeze the entire printer waiting for the bed to cool to 0 degrees.)
