In wl1271_probe(), 'glue->core' is allocated by platform_device_alloc(),
when this allocation fails, ENOMEM is returned. However, 'pdev_data'
and 'glue' are allocated by devm_kzalloc() before 'glue->core'. When
platform_device_alloc() returns NULL, we should also free 'pdev_data'
and 'glue' before wl1271_probe() ends to prevent leaking memory.

Similarly, we shoulf free 'pdev_data' when 'glue' is NULL. And we should
free 'pdev_data' and 'glue' when 'glue->reg' is error and when 'ret' is
error.

Further, we should free 'glue->core', 'pdev_data' and 'glue' when this 
function normally ends to prevent leaking memory.
