ide-dma: don't reset request fields on dma_timeout_retry()
Impact: drop unnecessary code Now that everything uses bio and block operations, there is no need to reset request fields manually when retrying a request. Every field is guaranteed to be always valid. Drop unnecessary request field resetting from ide_dma_timeout_retry(). Signed-off-by: Tejun Heo <tj@kernel.org>
