lttng-modules: Fix 3.14 bio tracepoints
The mainline 3.14 commit 'block: Astract out bvec iterator' broke the lttng-modules tracepoints. Fix them here. (From OE-Core rev: c11b29ff4f24af0445c3c6a694b8dc2037dcd7e4) Signed-off-by: Tom Zanussi <tom.zanussi@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

3In 3.14, bi_sector and bi_size were moved into an iterator, thus
4breaking any tracepoints that still expect them in the bio. Fix up
5the lttng-module tracepoints to use the new scheme when the kernel
6version is >= 3.14.
