lttng-modules: Fix do_compile failure for btrfs related tracepoints

Building lttng-modules with linux-yocto-dev will cause do_compile
failure:

lttng-modules/2.10.6-r0/lttng-modules-2.10.6/probes/../probes/lttng-tracepoint-event-impl.h:143:6: error: conflicting types for 'trace_btrfs_reserve_extent'
 void trace_##_name(_proto);
      ^~~~~~

functions' prototype.
