btrfs: reduce the number of arguments to btrfs_run_delalloc_range
Instead of a separate page_started argument that tells the callers that
btrfs_run_delalloc_range already started writeback by itself, overload
the return value with a positive 1 in additio to 0 and a negative error
code to indicate that is has already started writeback, and remove the
nr_written argument as that caller can calculate it directly based on
the range, and in fact already does so for the case where writeback
wasn't started yet.
