[iwl-next v3 7/8] iavf: use libie_aq_str

[Michal Swiatkowski <michal.swiatkowski@linux.intel.com>]

There is no need to store the err string in hw->err_str. Simplify it and
use common helper. hw->err_str is still used for other purpouse.

It should be marked that previously for unknown error the numeric value
was passed as a string. Now the "LIBIE_AQ_RC_UNKNOWN" is used for such
cases.

Add libie_aminq module in iavf Kconfig.
