[AX.25]: Make asc2ax() thread-proof
Asc2ax was still using a static buffer for all invocations which isn't
exactly SMP-safe. Change asc2ax to take an additional result buffer as
the argument. Change all callers to provide such a buffer.
This one only really is a fix for ROSE and as per recent discussions
there's still much more to fix in ROSE ...
