btrfs: remove EXTENT_UPTODATE io tree flag

Browse Source 
The EXTENT_UPTODATE io tree flag is now used only to mark ranges in the
fs_info->excluded_extents as used by super blocks and not available for
extent allocation (to prevent adding those ranges as free space in the
in memory space caches). As we can use any flag for that purpose, and
we are using EXTENT_DIRTY for the pinned extents io tree for example,
remove the EXTENT_UPTODATE flag and use instead EXTENT_DIRTY for the
excluded extents io tree.
