mount: proc-parse -- Show @mnt_id on debug print as well

This is convenient when need to lookup into debug prints
and check which mount point were used somewhere else
(in particular I will need @mnt_id in tty code so
 on error I can easily figure out which mountpoint has
 been used).

No func changes.
