datapath: Revert "datapath: rhel: Account for RHEL specific backports"
		
This reverts commit 752378e1cd1f133a8366fbacec3b281a45ff8268
(datapath: rhel: Account for RHEL specific backports).
Change related to netif_needs_gso() is cuasing panic on RHEL
and Xen platforms.  This way we revert back to use of ovs
skb_gso_segment() and netif_skb_features() which has required
compat code for gso for kernel older than 2.6.38.
