keys: fix missing __user in KEYCTL_PKEY_QUERY

The arg5 of KEYCTL_PKEY_QUERY should have a __user pointer tag on it as it is a user pointer. This clears the following sparse warning for this: security/keys/keyctl.c:1755:43: warning: incorrect type in argument 3 (different address spaces) security/keys/keyctl.c:1755:43: expected struct keyctl_pkey_query [noderef] <asn:1>*<noident> security/keys/keyctl.c:1755:43: got struct keyctl_pkey_query *<noident> Signed-off-by: Ben Dooks <[email protected]> Acked-by: Serge Hallyn <[email protected]> Signed-off-by: James Morris <[email protected]>
