/**
 * spectral_get_vdev() - Get pointer to vdev to be used for Spectral
 * operations
 * @pdev: Pointer to pdev
 * @vdev_id: vdev_id
 *
 * Spectral operates on pdev. However, in order to retrieve some WLAN
 * properties, a vdev is required. To facilitate this, the function returns the
 * first vdev in our pdev. The caller should release the reference to the vdev
 * once it is done using it. Additionally, the caller should ensure it has a
 * reference to the pdev at the time of calling this function, and should
 * release the pdev reference either after this function returns or at a later
 * time when the caller is done using pdev.
 * TODO:
 *  - If the framework later provides an API to obtain the first active
 *    vdev, then it would be preferable to use this API.
 *  - Use a common get_vdev() handler for core and target_if using Rx ops. This
 *    is deferred till details emerge on framework providing API to get first
 *    active vdev.
 *
 * Return: Pointer to vdev on success, NULL on failure
