pc-bios/s390-ccw: Clean up harmless misuse of isdigit()
atoui() and get_index() pass char values to isdigit(). With a
standard isdigit(), we'd get undefined behavior when the value is
negative. Can't happen as char is unsigned on s390x. Even if it
ould, we're actually using isdigit() from pc-bios/s390-ccw/libc.h
here, which works fine for negative values. Clean up anyway, just
to avoid setting a bad example.
