When closing a loop device, the kernel will asynchronously remove the probed partitions. This can lead to race conditions where we try to reuse a partition device that still needs to be removed by the kernel. To avoid such issues, let's explicitly try to remove any partitions using BLKPG_DEL_PARTITION when we're done with an image. To make sure we don't try to remove partitions when we want them to remain (e.g. systemd-dissect --mount), we add dissected_image_relinquish() in a similar vein to loop_device_relinquish() and decrypted_image_relinquish().
