Dan Rosenberg 73c9362424 x25: Prevent crashing when parsing bad X.25 facilities
commit 5ef41308f9 upstream.

Now with improved comma support.

On parsing malformed X.25 facilities, decrementing the remaining length
may cause it to underflow.  Since the length is an unsigned integer,
this will result in the loop continuing until the kernel crashes.

This patch adds checks to ensure decrementing the remaining length does
not cause it to wrap around.
