[RFC obexd 1/3] core: Fix queueing packet containing error while suspended

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Queueing the error won't remove the original packet created by transfer
from the queue so upon resume gobex will attempt to send it again.

To fix this we no longer create a error packet instead the session is
market as aborted and the error stored so when gobex finally resumes the
error is forward properly.
