[PATCH v4 05/10] crypto: iaa - Disable iaa_verify_compress by default.

[Kanchana P Sridhar <kanchana.p.sridhar@intel.com>]

This patch makes it easier for IAA hardware acceleration in the iaa_crypto
driver to be loaded by default with "iaa_verify_compress" disabled, to
facilitate performance comparisons with software compressors (which also
do not run compress verification by default). Earlier, iaa_crypto compress
verification used to be enabled by default.

With this patch, if users want to enable compress verification, they can do
so with these steps:

  1) disable all the IAA device/wq bindings that happen at boot time
  2) rmmod iaa_crypto
  3) modprobe iaa_crypto
  4) echo 1 > /sys/bus/dsa/drivers/crypto/verify_compress
  5) re-run initialization of the IAA devices and wqs
