[PATCH v2 1/1] ml/cnxk: fix reporting of incorrect error info

[Srikanth Yalavarthi]

In the rte_ml_op_error_get driver function, the errcode
field of rte_ml_op_error structure is not being updated.
This is causing an incorrect or junk value being reported
as errcode to caller.

For error subtype not supported by driver, the error
message reported is incorrect or junk.

Fixes: 57c37b852f2c ("ml/cnxk: support firmware error code query")
