Btrfs: fix wrong super generation mismatch when scrubbing supers
We came a race condition when scrubbing superblocks, the story is:
In commiting transaction, we will update @last_trans_commited after
writting superblocks, if scrubber start after writting superblocks
and before updating @last_trans_commited, generation mismatch happens!
We fix this by checking @scrub_pause_req, and we won't start a srubber
until commiting transaction is finished.(after btrfs_scrub_continue()
finished.)
