Bluetooth: Fix resource leak in OPP (3/3)

- This patch handles closing of input stream if no device is selected
  by user when trying to send file via BT. Without this patch, input
  stream was never closed resulting in leak with each iteration and
  system crash after 1024 iterations.

- This change will remove hashmap share entry if user selected share
  via BT and press back or press cancel. Otherwise, hashmap will reach
  its limit for successive share via BT and cause BT app to crash.
