i40e: Memory leak in i40e_config_iwarp_qvlist

Browse Source 
[ Upstream commit 0b63644602 ]

Added freeing the old allocation of vf->qvlist_info in function
i40e_config_iwarp_qvlist before overwriting it with
the new allocation.

Fixes: e3219ce6a7 ("i40e: Add support for client interface for IWARP driver")
