cleanup: move error handling into write_retry
If write_retry fails to write everything, it is *always* an error. This commit renames write_retry to write_data and moves error handling into the function, making a lot of error handling code redundant. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
