w1: small type cleanup in sysfs
On 64 bit systems, a large value for "long tmp" is truncated when assigning to "int md->max_slave_count" so we still end up with a value less than one despite the "tmp < 1" check. This is more of a problem for static checkers than a real life issue, but it's simple enough to fix.
