Commit 7988e5ae2be7 ("tick: Split nohz and highres features from
nohz_mode") and commit 7988e5ae2be7 ("tick: Split nohz and
highres features from nohz_mode") move 'tick_stopped' and 'nohz_mode'
to flags field which will break the gdb lx-mounts command:
(gdb) lx-timerlist
Python Exception <class 'gdb.error'>: There is no member named nohz_mode.
Error occurred in Python: There is no member named nohz_mode.
(gdb) lx-timerlist
Python Exception <class 'gdb.error'>: There is no member named tick_stopped.
Error occurred in Python: There is no member named tick_stopped.
We move 'tick_stopped' and 'nohz_mode' to flags field instead.

Fixes: 7988e5ae2be7 ("tick: Split nohz and highres features from nohz_mode")
