[Crash-utility] [PATCH] Fix for "help -m" option to display correct hz value
Kernel commit 3e9a99eba058 ("block/mq-deadline: Rename dd_init_queue()
and dd_exit_queue()") renamed dd_init_queue to dd_init_sched. Without
the patch, the 'help -m' may print incorrect hz value as follows:
crash> help -m | grep hz
hz: 1000 <---The correct hz value on ppc64le machine is 100.
^^^^
Fixes: b93027ce5c75 ("Add alternate HZ calculation using write_expire")
