hw/sd/sdhci: Reset @data_count index on invalid ADMA transfers
We neglected to clear the @data_count index on ADMA error, allowing to trigger assertion in sdhci_read_dataport() or sdhci_write_dataport(). Cc: qemu-stable@nongnu.org Fixes: d7dfca0807 ("hw/sdhci: introduce standard SD host controller") Reported-by: Zheyu Ma <zheyuma97@gmail.com> Resolves: https://gitlab.com/qemu-project/qemu/-/issues/2455 Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20240730092138.32443-4-philmd@linaro.org> (cherry picked from commit ed5a159c3de48a581f46de4c8c02b4b295e6c52d) Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
