[PATCH v4 0/2] btrfs: fix periodic reclaim condition

[Sun YangKai <sunk67188@gmail.com>]

This series eliminates wasteful periodic reclaim operations that were occurring
when already failed to reclaim any new space, and includes several preparatory
cleanups.

Patch 1 fixes the core issue.
Patch 2 is a trival cleanup.

Changelog

v4:
- Remove setting periodic_reclaim_ready to false when failed to reclaim a
  blockgroup since it's unnecessary. Sugggested by Boris Burkov <boris@bur.io>

v3:
- Fix the core issue with minimal changes, suggested by Boris Burkov <boris@bur.io>
- Drop some cleanups which might conflict with some other recent patches
  in mail list. I'll send them in a seperate serie.
