HID: Handle collisions during incoming and outgoing connections

- This patch handles cases when incoming HID connection is in progress, and
  there is an outgoing connection attempt from upper layers. This was leading
  to a case when ougoing connection would fail as connection was already in
  progress, which triggered cleanup of connection states, which was not proper
  leading to issues in future connection attempts, as disconnection during
  ongoing connection was not handled properly in existing code.

- Reset the incoming flags during open failure to prevent any possible issues
  during further outgoing connections.
