Sound: hda - Restore PCI configuration space with interrupts off

Move the restoration of the standard PCI configuration registers
in the snd_hda_intel driver to a ->resume_early() callback executed
with interrupts disabled, since doing that with interrupts enabled
may lead to problems in some cases.

This patch addresses the regression from 2.6.26 tracked as
http://bugzilla.kernel.org/show_bug.cgi?id=12121 .
