fs/block_dev.c: return the right error in thaw_bdev()
When triggering thaw-filesystems via magic sysrq, the system enters a loop in do_thaw_one(), as thaw_bdev() still returns success if bd_fsfreeze_count == 0. To fix this, let thaw_bdev() always return error (and simplify the code a bit at the same time).
