Subject: [ 10/53] xen/netback: check correct frag when looking for head frag

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ian Campbell <ian.campbell@...rix.com>

When I backported 7d5145d8eb2b "xen/netback: don't leak pages on failure in
xen_netbk_tx_check_gop" to 3.0 (where it became f0457844e605) I somehow picked
up an extraneous hunk breaking this.
