xfs: Add caller function output to xfs_log_force tracepoint

Browse Source 
I had sent this patch yesterday, but for some reason it didn't reach
xfs list, sending again.

Output the caller of xfs_log_force might be useful when tracing log
checkpoint problems without the need to build kernel with DEBUG.
