MTP: enable new cancel behavior in short packet handling

Since short packet handling still use older cancel bahavior,
the cancel may be failed if users copy specific files to the
PC.

This patch will send batchcancel flag to cancelEvents in
short packet handling so that cancelEvents function will
select the cancel behavior by batchcancel flag.
