[PATCH 3/4] xen: netback: drop frag member from struct netbk_rx_meta

[Ian Campbell <ian.campbell@citrix.com>]

It has been unused since c3219dc "xen/netback: completely drop flip
support", as has netbk_free_pages().

(Although it now has only a single member struct netbk_rx_meta will
gain other members in a subsequent patch so there is no point
reworking to get rid of the struct)
