badblocks: fix missing bad blocks on retry in _badblocks_check()

Browse source

The bad blocks check would miss bad blocks when retrying under contention,
as checking parameters are not reset. These stale values from the previous
attempt could lead to incorrect scanning in the subsequent retry.

Move seqlock to outer function and reinitialize checking state for each
retry. This ensures a clean state for each check attempt, preventing any
missed bad blocks.
