With vmalloc stack addresses enabled (CONFIG_VMAP_STACK=y) DCP trusted keys can crash during en- and decryption of the blob encryption key via the DCP crypto driver. This is caused by improperly using sg_init_one() with vmalloc'd stack buffers (plain_key_blob).
Fix this by always using kmalloc() for buffers we give to the DCP crypto driver.

gentle ping.
It's done, thanks for reminding, and don't hesitate to do it earlier if this ever happens again.
I.e. I applied and will put to my PR.
