mISDN: fix sparse warnings

Impact: change data type for variable 'debug' from *int to *u_int, same for the argument type of mISDN_inittimer

In "core.h" mISDN_inittimer is declared with the argument type "*u_int", make the definition in "timerdev.c" match this.

This fixes also this warnings:

drivers/isdn/mISDN/layer1.c:391:8: warning: incorrect type in assignment (different signedness)
drivers/isdn/mISDN/layer1.c:391:8: expected int *static [toplevel] debug
