btrfs: stop using lock_extent in btrfs_buffer_uptodate
The only other place that locks extents on the btree inode is
read_extent_buffer_subpage while reading in the partial page for a
buffer. This means locking the extent in btrfs_buffer_uptodate does not
synchronize with anything on non-subpage file systems, and on subpage
file systems it only waits for a parallel read(-ahead) to finish,
which seems to be counter to what the callers actually expect.
