libertas: check return value of alloc_workqueue Function alloc_workqueue() will return a NULL pointer if there is no enough memory, and its return value should be validated before using. However, in function if_spi_probe(), its return value is not checked. This may result in a NULL dereference bug. This patch fixes the bug.
