btrfs: remove hole check in prealloc_file_extent_cluster
Extents in the extent cluster are guaranteed to be contiguous as such the hole check inside the loop can never trigger. In fact this check was never functional since it was added in18513091af
("btrfs: update btrfs_space_info's bytes_may_use timely") which came after the commit introducing clustered/contiguous extents0257bb82d2
("Btrfs: relocate file extents in clusters"). Let's just remove it as it adds noise to the source. Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Signed-off-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
