reset: tegra-bpmp: Restore Handle errors in BPMP response
[ Upstream commit d1da1052ffad63aa5181b69f20a6952e31f339c2 ]
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.
