bnxt_en: parse and report result field when NVRAM package install fails

bnxt_en: parse and report result field when NVRAM package install fails

Instead of always returning -ENOPKG, decode the firmware error
code further when the HWRM_NVM_INSTALL_UPDATE firmware call fails.
Return a more suitable error code to userspace and log an error
in dmesg.

This is version 2 of the earlier patch that was reverted:

843eb3be9581 ("bnxt_en: parse result field when NVRAM package install fails")

In this new version, if the call is made through devlink instead of
ethtool, we'll also set the error message in extack.
