btrfs-progs: device add should check existing FS before adding
as of now, when 'btrfs device add' adds a device it doesn't
check if the given device contains an existing FS. This
patch will change that to check the same. which when true
add will fail, and ask user to use -f option to overwrite.
further, since now we have test_dev_for_mkfs() function
to check if a disk can be used, so this patch will also
use this function to test the given device before adding.
