security/keys: Remove inconsistent __user annotation

The declaration of keyring_read does not match the definition
(security/keys/keyring.c). In this case the definition is correct
because it matches what defined in "struct key_type::read"
(linux/key-type.h).

Fix the declaration removing the inconsistent __user annotation.
