i40e: use ERR_PTR error print in i40e messages

[ Upstream commit d5ba1842 ]

In i40e_status removal patches, i40e_status conversion
to strings was removed in order to easily refactor
the code to use standard errornums. This however made it
more difficult for read error logs.

Use %pe formatter to print error messages in human-readable
format.
