This reverts following commit 69125b4b9440 ("reset: tegra-bpmp: Revert
Handle errors in BPMP response").
The Tegra194 HDA reset failure is fixed by commit d278dc9151a0 ("ALSA:
hda/tegra: Fix Tegra194 HDA reset failure"). The temporary revert of
original commit c045ceb5a145 ("reset: tegra-bpmp: Handle errors in BPMP
response") can be removed now.

Hi Philipp,
the commit that fixed the HDA reset failure was merged into v5.17-rc1,
so this can safely be applied as a fix for v5.17. At the same time the
existing bug is fairly harmless, so deferring this to v5.18 would also
be fine.
