Subject: [PATCH] ewrk3: silence GCC warning

Building ewrk3.o triggers this GCC warning:
    drivers/net/ethernet/dec/ewrk3.c: In function '__check_irq':
    drivers/net/ethernet/dec/ewrk3.c:1915:1: warning: return from incompatible pointer type [enabled by default]

This can be trivially fixed by changing the 'irq' parameter from int to
byte (which is the alias for unsigned char for module parameters).

While we're touching this code also drop an outdated comment, that
should have been dropped with the patch named "MODULE_PARM conversions"
from early 2005.
