Root Cause:
Input stream was never closed resulting in leak with each iteration and system crash after 1024 iterations.

Fix:
Handle closing of input stream and Remove hashmap share if no device is selected by user when trying to send
file via BT. Without this, input stream was never closed resulting in leak with each iteration and system crash
after 1024 iterations.

Test: Performed the usecase overnight and see if no crash is observed.
