On an fs mounted using a sprout device, the seed fs_devices are maintained in a linked list under fs_info->fs_devices. Each seeds fs_devices also has device_list_mutex initialized to protect against the potential race with delete threads. But the delete thread (at btrfs_rm_device()) is holding the fs_info::fs_devices::device_list_mutex mutex which belongs to sprout device_list_mutex instead of seed device_list_mutex. Moreover, there aren't any significient benefits in using the seed::device_list_mutex instead of sprout::device_list_mutex. So this patch converts them of using the seed::device_list_mutex to sprout::device_list_mutex.
