[v3,7/7] net/bnxt: fix to not overwrite error message

  In some cases when flow creation fails, we  overwrite the specific
error message with a generic error message. This patch fixes it.

Fixes: d24610f7bfda ("net/bnxt: allow flow creation when RSS is enabled")
Cc: stable@dpdk.org

The result will be same as far as I can see, you may get rid of the "rc =
-rte_errno;" assignments before "goto ret;" with this change if you want.

Also commit log seems describing the below change not this one ...
