s/MAX_DEVICES/MAXDEVICES/ updates.

Browse Source 
The number of input devices is MAXDEVICES, not MAX_DEVICES (f781a752e6)
Two comments updated to refer to MAXDEVICES.

MAX_FUNCS in sigio.c was set to 16 if MAX_DEVICES was undefined. If more
than 15 physical input devices were present, this could result in a
failure to install the SIGIO handler for any device above 15.
