[PATCH 1/3] btrfs: Remove hole check in prealloc_file_extent_cluster

[Nikolay Borisov <nborisov@suse.com>]

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 in 18513091af948 which came
after the commit introducing clustered/contiguous extents: 0257bb82d21b.

Let's just remove it as it adds noise to the source.
