[PATCH v2 5/6] net/iavf: fix leak of flex metadata extraction field

[Bruce Richardson <bruce.richardson@intel.com>]

Function iavf_init_proto_xtr() allocates vf->proto_xtr as part of the
device init sequence, but no shutdown function frees this memory again.
Add an appropriate free call to fix this memory leak.
