ALSA: hda - fix use-after-free after module unload
register_vga_switcheroo() sets the PM ops from the hda structure which
is freed later in azx_free. Make sure that these ops are cleared.
Caught by KASAN, initially noticed due to a general protection fault.
Fixes: 246efa4a072f ("snd/hda: add runtime suspend/resume on optimus support (v4)")
