Bluetooth: msft: fix slab-use-after-free in msft_do_close()

Tying the msft->data lifetime to hdev by freeing it in hci_release_dev() to fix the following case:

[use] msft_do_close() msft = hdev->msft_data; if (!msft) ...(1) <- passed. return; mutex_lock(&msft->filter_lock); ...(4) <- used after freed.

[free] msft_unregister() msft = hdev->msft_data; hdev->msft_data = NULL; ...(2) kfree(msft); ...(3) <- msft is freed.
