Use the new resource-managed variant of blk_ksm_init() so that the UFS
driver doesn't have to manually call blk_ksm_destroy().

I took the liberty of applying this one to my mmc tree along with
patch1, as it looks trivial to me.

Martin/James - if you have objections or want to ack it, please tell me.

Thanks and kind regards
