From: Julien Grall <jgrall@amazon.com>

The command line option -M/--path-max was meant to be added by
commit 924bf8c793cb "tools/xenstore: rework path length check" but this
wasn't wired through properly.

Fix it by adding the missing "case 'M':".

Thanks! I have committed it.

Coverity actually spotted it (see CID-1470790) back in December 2020. 
Although, I wasn't aware of it because I just check coverity now.
