selftests: ublk: add helper for SET_PARAMS

Browse source

The normal kublk add command goes through device startup. It does not
tell the shell test whether a bad parameter is rejected by SET_PARAMS or
later by START_DEV.

Add a set_params command. It creates a temporary ublk device, sends
SET_PARAMS with the command line parameters, returns the ioctl result,
and deletes the device before START_DEV.
