Test generic/019 produces some disk failures so sumbit dio will get errors, in which case, btrfs_direct_IO() goes to the error handling and free bytes_may_use, but the problem is that bytes_may_use has been free'd during get_block(). This adds a runtime flag to show if we've gone through get_block(), if so, don't do the cleanup work.
