Mark proper file transfer status upon OBEX response timeout

Use Case:
1) Pair with remote dongle and send a file over OPP.
2) Reset dongle such that there is obex response timeout.

Failure:
File transfer status is not marked a failed and hence cannot be retried

Fix:
This patch will handle the scenario of obex timeout which occurs due
to cancelling the transfer in between and trying sending again.
