Details:

The implementation of netbuf_destport() is not correct when
LWIP_NETBUF_RECVINFO is enabled, but not LWIP_CHECKSUM_ON_COPY

The flags field is only available when LWIP_CHECKSUM_ON_COPY is enabled and
thus we shouldn't check it in netbuf_destport() when only LWIP_NETBUF_RECVINFO
is enabled

Attached is a patch that adds an alternate definition of netbuf_destport()
when only LWIP_NETBUF_RECVINFO is enabled
