w1: do not unlock unheld list_mutex in __w1_remove_master_device()
w1_process_callbacks() expects to be called with dev->list_mutex held, but it is the fact only in w1_process(). __w1_remove_master_device() calls w1_process_callbacks() after it releases list_mutex. The patch fixes __w1_remove_master_device() to acquire list_mutex for w1_process_callbacks(). Found by Linux Driver Verification project (linuxtesting.org).
