[PATCH 6.6.y 1/7] usb: typec: ucsi: move ucsi_acknowledge() from ucsi_read_error()

[Sasha Levin <sashal@kernel.org>]

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

[ Upstream commit a7d2fa776976294d39d4cf36b25ca43be8325c3f ]

As a preparation for reworking UCSI command handling, move
ucsi_acknowledge() for the failed command from ucsi_read_error() to
ucsi_exec_command().
