dm cache: only allow a single io_mode cache feature to be requested
More than one io_mode feature can be requested when creating a dm cache
device (as is: last one wins). The io_mode selections are incompatible
with one another, we should force them to be selected exclusively. Add
a counter to check for more than one io_mode selection.
Fixes: 629d0a8a1a10 ("dm cache metadata: add "metadata2" feature")
