[PATCH] xen/arm: traps: Don't panic when receiving an unknown debug trap

[Julien Grall]

From: Julien Grall <jgr...@amazon.com>

Even if debug trap are only meant for debugging purpose, it is quite
harsh to crash Xen if one of the trap sent by the guest is not handled.

So switch from a panic() to a printk().
