gve: rename gve_xdp_xmit to gve_xdp_xmit_gqi

Browse Source 
In preparation for XDP DQ support, the gve_xdp_xmit callback needs to
be generalized for all queue formats. This patch renames the GQ-specific
function to gve_xdp_xmit_gqi, and introduces a new gve_xdp_xmit callback
which branches on queue format.
