hdaudio1: RIRB timeout in 8.0_BETA

["Gary Duzan" <gary%duzan.org@localhost>]

   After upgrading from an earlier netbsd-8 snapshot, I got this on reboot:

[...]

   There were enough timeout messages to overflow past the top of
the dmesg buffer, but here is the uname:

NetBSD capo.xnet.duzan.org 8.0_BETA NetBSD 8.0_BETA (GENERIC) #4: Fri Jun 30 08:42:43 EDT 2017  root%bldr.6net.duzan.org@localhost:/usr/build/netbsd-8/obj/usr/build/netbsd-8/src/sys/arch/amd64/compile/GENERIC amd64

   I get the same message when I try to play any audio. Does this
ring any bells, or should I go ahead and send-pr it?

   Thanks.
