ip: fix offload flags handling
The per-protocol offload flags only make sense if F_OFFLOAD is set on
the vlib buffer main flags.
vnet_calc_checksums_inline is called from many places which should do
this check and don't, moving the check to this function is less error
prone and shouldn't have an impact on performance since the function
is always_inline.
Type: fix
