ionic: Allow flexibility for error reporting on dev commands

When dev commands fail, an error message will always be printed,
which may be overly alarming the to system administrators,
especially if the driver shouldn't be printing the error due
to some unsupported capability.

Similar to recent adminq request changes, we can update the
dev command interface with the ability to selectively print
error messages to allow the driver to prevent printing errors
that are expected.
