ALSA: hda/i915: Fix one too many pci_dev_put()
pci_get_class() will already unref the pci device passed as argument.
So if it's unconditionally unref'ed, even if the loop is not stopped,
there will be one too many unref for each device not matched.
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5701
Fixes: c9db8a30d9f0 ("ALSA: hda/i915 - skip acomp init if no matching display")
