sched: fix signedness warnings in sched.c

Unsigned long values are always assigned to switch_count,
make it unsigned long.

kernel/sched.c:3897:15: warning: incorrect type in assignment (different signedness)
kernel/sched.c:3897:15:    expected long *switch_count
kernel/sched.c:3897:15:    got unsigned long *<noident>
kernel/sched.c:3921:16: warning: incorrect type in assignment (different signedness)
kernel/sched.c:3921:16:    expected long *switch_count
kernel/sched.c:3921:16:    got unsigned long *<noident>
