Remove checks on MAX_SERIAL_PORTS that are just bounds checks

Browse source 
Remove checks on MAX_SERIAL_PORTS that were just checking whether
they were within bounds for the serial_hds[] array and falling
back to NULL if not. This isn't needed with the serial_hd()
function, which returns NULL for all indexes beyond what the
user set up.
