btrfs: do not require EXTENT_NOWAIT for btrfs_redirty_list_add()
The flag EXTENT_NOWAIT is a special flag to notify extent-io-tree code
that this operation should not sleep for the extent state preallocation.
However for btrfs_redirty_list_add(), all callers are able to sleep:
- clean_log_buffer()
Just 2 lines before, we call btrfs_pin_reserved_extent(), which calls
pin_down_extent(), and that function does not require EXTENT_NOWAIT.
Thus we're safe to call it without EXTENT_NOWAIT.
- btrfs_free_tree_block()
This function have several call sites which trigger tree read, e.g.
walk_up_proc(), thus we're safe to call it without EXTENT_NOWAIT.
Thus there is no need to require EXTENT_NOWAIT flag.
