[PATCH 2/2] btrfs: Remove always true condition in btrfs_start_delalloc_roots

[Nikolay Borisov <nborisov@suse.com>]

Following the rework in
"btrfs: shrink delalloc pages instead of full inodes" the nr variable
is no longer passed by reference to start_delalloc_inodes hence it
cannot change. Additionally we are always guaranteed for it to be
positive number hence it's redundant to have it as a condition in the
loop. Simply remove that usage.
