libata: add extra internal command
Bump the internal tag to 32, instead of stealing the last tag in
our regular command space. This works just fine, since we don't
actually need a separate hardware tag for this. Internal commands
cannot coexist with NCQ commands.
As a bonus, we get rid of the special casing of what tag to use
for the internal command.
This is in preparation for utilizing all 32 commands for normal IO.
