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.
