net: Fix vti use case with oif in dst lookups
Steffen reported that the recent change to add oif to dst lookups breaks the VTI use case. The problem is that with the oif set in the flow struct the comparison to the nh_oif is triggered. Fix by splitting the FLOWI_FLAG_VRFSRC into 2 flags -- one that triggers the vrf device cache bypass (FLOWI_FLAG_VRFSRC) and another telling the lookup to not compare nh oif (FLOWI_FLAG_SKIP_NH_OIF).
