FTP: Remove pending user timeout intent on ACL disconnected

This patch fixes the following issues in FTP Code:
   - MSG_INTERNAL_USER_TIMEOUT intent is removed on reception of
     ACL disconnected. Previously this message was not removed and
     new intent was sent to stop obex server resulting in rfcomm
     socket being listened 2 times from ftp service in case ACL is
     disconnected while waiting for authorization.
   - Rfcomm accept thread is closed properly and joined instead of
     making it null on stopObexServer. this might be leading to some
     synchronization issues, as thread variable was made zero before
     it was closed.
   - VERBOSE logging was not shown, so removed all the logs from the
     flag for BluetoothFtpService.java.
