bnxt_en: reserve space inside receive page for skb_shared_info
Insufficient space was being reserved in the page used for packet
reception, so the interface MTU could be set too large to still have
room for the contents of the packet when doing XDP redirect. This
resulted in the following message when redirecting a packet between
3520 and 3822 bytes with an MTU of 3822:
[311815.561880] XDP_WARN: xdp_update_frame_from_buff(line:200): Driver BUG: missing reserved tailroom
Fixes: f18c2b77b2e4 ("bnxt_en: optimized XDP_REDIRECT support")
