binder: protect against stale pointers in print_binder_transaction When printing transactions there were several race conditions that could cause a stale pointer to be deferenced. Fixed by reading the pointer once and using it if valid (which is safe). The transaction buffer also needed protection via proc lock, so it is only printed if we are holding the correct lock.
