uni-t-ut32x: drop redundant close and free at end of scan
The UT32x driver requires a user spec for the connection. The device
cannot get identified, that's why successful open/close for the port
will suffice. Lack of an input spec as well as failure in the early
scan phase will terminate the scan routine early.
When we reach the end of the scan which creates the device instance
and registers it with the list of found devices, the port already
is closed and the list of devices will never be empty. Remove the
redundant close call and the dead branch which frees the serial port.

bt/bt_bluez: Implement retry if rfcomm sockets are busy
There are cases where the connect() call returns EBUSY when trying to
connect to a device. This has been observed when sampling an RDTech
UM24C. In this case, scanning the device works fine. However, when
sampling the device, Sigrok first scans the device, then closes the
connection and re-opens it to sample the device. If the close/open
calls happen in close successions, the Bluetooth stack sometimes
returns EBUSY.
Work around this issue by retrying if the connect() returns EBUSY.
Since the device should be closed after the scan, close it in sr_modbus_scan.
Alternatively, every single driver could close the device after calling
sr_modbus_scan. This causes duplicated code, is prone to forgetting it and it
wasn't the calling driver who opened the device in the first place.
