crypto: iaa - Fix some errors in IAA documentation

This cleans up the following issues I ran into when trying to use the
scripts and commands in the iaa-crypto.rst document.

- Fix incorrect arguments being passed to accel-config
  config-wq.
    - Replace --device_name with --driver-name.
    - Replace --driver_name with --driver-name.
    - Replace --size with --wq-size.
    - Add missing --priority argument.
- Add missing accel-config config-engine command after the
  config-wq commands.
- Fix wq name passed to accel-config config-wq.
- Add rmmod/modprobe of iaa_crypto to script that disables,
  then enables all devices and workqueues to avoid enable-wq
  failing with -EEXIST when trying to register to compression
  algorithm.
- Fix device name in cases where iaa was used instead of iax.
