vsc_identify_silicon() returns -EINVAL in various places without logging
what is going on.
And there are several bug reports about mei_vsc_hw_reset() failing with
-EINVAL before the "silicon stepping version is %u:%u" message get logged,
indicating this is coming from vsc_identify_silicon():
[ 10.949657] intel_vsc intel_vsc: hw_reset failed ret = -22
[ 10.988899] intel_vsc intel_vsc: hw_reset failed ret = -22
[ 11.027140] intel_vsc intel_vsc: hw_reset failed ret = -22
[ 11.027151] intel_vsc intel_vsc: reset: reached maximal consecutive resets: disabling the device
[ 11.027155] intel_vsc intel_vsc: reset failed ret = -19
[ 11.027157] intel_vsc intel_vsc: link layer initialization failed.
[ 11.027159] intel_vsc intel_vsc: error -ENODEV: init hw failed
Add proper error logging to mei_vsc_hw_reset() so that it will be clear
why it is failing when it fails.
