[Asterisk-code-review] dundi: fix NULL dereference. (asterisk[master])

[Jaco Kroon]

Hello George Joseph, Friendly Automation, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/c/asterisk/+/13948

to look at the new patch set (#2).

Change subject: dundi:  fix NULL dereference.
......................................................................

dundi:  fix NULL dereference.

If a negative (error) return is received from dundi_lookup_internal,
this is not handled correctly when assigning the result to the buffer.
As such, use a signed integer in the assignment and do a proper
comparison.

ASTERISK-21205
