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);
^~~~~~
The following commit from latest mainline kernel changes some btrfs
functions' prototype.
3dca5c942dac60164e6a6e89172f25b86af07ce7
"btrfs: trace: Remove unnecessary fs_info parameter for btrfs__reserve_extent event class"
This patch backports a commit from upstream to meet the above changes.
