[PATCH 4/7] btrfs: consolidate reclaim readiness checks in btrfs_should_reclaim()

[Sun YangKai <sunk67188@gmail.com>]

Move the filesystem state validation from btrfs_reclaim_bgs_work() into
btrfs_should_reclaim() to centralize the reclaim eligibility logic.
Since it is the only caller of btrfs_should_reclaim(), there's no
functional change.
