If the dm_resume method is called on a device that is not suspended, the method will suspend the device briefly, before resuming it (so that the table will be swapped). However, there was a bug that the return value of dm_suspended_md was not checked. dm_suspended_md may return an error when it is interrupted by a signal. In this case, do_resume would call dm_swap_table, which would return -EINVAL. This commit fixes the logic, so that error returned by dm_suspend is checked and the resume operation is undone.
