bnxt_en: add more error checks to HWRM_NVM_INSTALL_UPDATE

FW returns error code "NVM_INSTALL_UPDATE_CMD_ERR_CODE_ANTI_ROLLBACK"
in the response to indicate that HWRM_NVM_INSTALL_UPDATE command has
failed due to Anti-rollback feature. Parse the error and return an
appropriate error code to the user.
