xfs: fix broken log reservation debugging
xlog_print_tic_res() is supposed to print a human readable string for each element of the log ticket reservation array. Unfortunately, I forgot to update the string array when we added rmap & reflink support, so the debug message prints "region[3]: (null) - 352 bytes" which isn't useful at all. Add the missing elements and add a build check so that we don't forget again to add a string when adding a new XLOG_REG_TYPE. Signed-off-by: Darrick J.
