Currently btrfs_device is allocated ad-hoc in a few different places, and as a result not all fields are initialized properly. In particular, readahead state is only initialized in device_list_add (at scan time), and not in btrfs_init_new_device (when the new device is added with 'btrfs dev add'). Fix this by adding an allocation helper and switch everybody but __btrfs_close_devices to it. (__btrfs_close_devices is dealt with in a later commit.) Signed-off-by:
