KEYS: trusted: dcp: fix improper sg use with CONFIG_VMAP_STACK=y
commit e8d9fab39d1f87b52932646b2f1e7877aa3fc0f4 upstream.
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.
