Function btrfs_scan_devices() is being used by commands such as
'btrfs filesystem' and 'btrfs device', by having the verbose argument in
the btrfs_scan_devices() we can control which threads to print the
messages when verbose is enabled by the global option.
Add an option %verbose to btrfs_scan_devices().
