Test on CYW943438 with sdk-6.1.

To test if it is fine to repeat init/deinit bt_stack by calling wiced_bt_stack_init/wiced_bt_stack_deinit.

My test code is calling wiced_bt_ble_observe() once got BTM_ENABLED_EVT in the wiced_bt_stack_init callback.

The wiced_bt_ble_observe() scan for 10 seconds and once it is done.

Calling wiced_bt_stack_deinit and wiced_bt_stack_init again to re-start scan.

Observe the memory usage by mallinfo().

Then you can find the "Memory in use keep growth, the available memory becomes smaller and smaller.

i.e. It's clearly a memory leak while re-init bt stack.
