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.

devlink fw flashing allows for the msg to be reported directly 
to the user, that's more friendly than having to scan logs.
