ALSA: hda: Add missing sanity checks in PM prepare/complete callbacks

stable inclusion
from stable-5.10.28
commit 6d91f3afb632f9ebba134ec8934a47804b6b0267
bugzilla: 51779

--------------------------------

commit 66affb7b upstream.

The recently added PM prepare and complete callbacks don't have the
sanity check whether the card instance has been properly initialized,
which may potentially lead to Oops.

This patch adds the azx_is_pm_ready() call in each place
appropriately like other PM callbacks.
