OPP: Interrup Obex Client thread while sending ABORT

Precondition: PTS 7.2.1

Use case:
1. Execute test case TC_OPP_CL_OPH_BV_27_I for OPP
2. Try to cancel the transfer as requested by PTS, by cancelling the transfer.

Expectation:
Test case should pass

Observation:
Test case fails

Root cause:
While aborting put operation IO exception is seen
because of timeout and dut closes Obex session.

Fix:
First interrupt Obex client thread, during abort
request while file transfer is active.

Test: TC_OPP_CL_OPH_BV_27_I can be passed after the patch.
