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().
