Subject: [GIT PULL] Btrfs fix for 6.4-rc7, part 2

Hi,

unfortunately the recent u32 overflow fix was not complete, there was
one conversion left, assertion not triggered by my tests but caught by
Qu's fstests case. The "cleanup for later" has been promoted to a proper
fix and wraps all uses of the stripe left shift so the diffstat has grown
but leaves no potentially problematic uses. We should have done it that
way before, sorry.

Please pull, thanks.
