[XEN PATCH v2 2/2] tools/lsevtchn: Use new status identifiers in loop

[Matthew Barnes <matthew.barnes@xxxxxxxxx>]

lsevtchn terminates the loop when the hypercall returns an error, even
if there are still event channels with higher port numbers to be
enumerated over.

Continue the loop even on hypercall errors, and use the new status
identifiers for the evtchn_status hypercall, namely "port invalid" and
"domain invalid", to determine when to break the loop.
