i40e: Fix failed opcode appearing if handling messages from VF
commit 61125b8be85dfbc7e9c7fe1cc6c6d631ab603516 upstream.
Fix failed operation code appearing if handling messages from VF.
Implemented by waiting for VF appropriate state if request starts
handle while VF reset.
Without this patch the message handling request while VF is in
a reset state ends with error -5 (I40E_ERR_PARAM).
Fixes: 5c3c48ac6bf5 ("i40e: implement virtual device interface")
