ixgbe: prefer enabling olflags rather than not disabling

Browse Source 
RTE_IXGBE_RX_OLFLAGS_ENABLE gives a hint whick keeping packet type
in RX ol_flags or not.
By default it is set to update ol_flags in RX mbuf header.
If unset it, will gain addtional performance, but will lose packet
type information.
