w1: decrement slave counter only in ->release() callback
Decrement the slave counter only in ->release() callback instead of both
in ->release() and w1 control.
Patch is based on debug work and preliminary patch made by Henri Laakso.
Henri noticed in debug that this counter becomes negative after w1 slave
device is physically removed.
