[PATCH 14/30] W1: w1_therm consistent mutex access code cleanup

[Evgeniy Polyakov]

sl->master->mutex and dev->mutex refer to the same mutex variable, but
be consistent and use the same set of pointers for the lock and unlock
calls.  It is less confusing (and one less pointer dereference this
way).
