Subject: nfp: improve app not found message
Patch-mainline: v4.16-rc1
Git-commit: bf245f1fb085a17f93739452f017f9107d035a7e
References: bsc#1109837

When driver app matching loaded FW is not found users are faced with:

   nfp: failed to find app with ID 0x%02x

This message does not properly explain that matching driver code is
either not built into the driver or the driver is too old.
