[CRIU] [PATCH] mount: always report ->mnt_id as decimal

[Oleg Nesterov]

Cosmetic. but it took me MORE THAN ONE HOUR to realize that

	FS mnt ./boot dev 0xfc00001 root / unsupported id 67

has nothing to do with the 67 mnt I see in /proc/$pid/mountinfo and
in other parts of -vvvv output.

I thought that this ->mnt_id was corrupted or miscalculated somehow,
but after a lot of grepping I found the easter egg added by a giggling
criu developer from CC list.

Perhaps it makes sense to change fsnotify.c too, I dunno. But lets at
least make proc_parse.c and mount.c consistent wrt ->mnt_id reporting.

./boot looks a bit confusing to imo, may be ->mountpoint + 1 will look
a bit better, but this needs more changes.

Oleg.
