KEYS: Fix some sparse warnings
Fix some sparse warnings in the keyrings code: (1) compat_keyctl_instantiate_key_iov() should be static. (2) There were a couple of places where a pointer was being compared against integer 0 rather than NULL. (3) keyctl_instantiate_key_common() should not take a __user-labelled iovec pointer as the caller must have copied the iovec to kernel space. (4) __key_link_begin() takes and __key_link_end() releases keyring_serialise_link_sem under some circumstances and so this should be declared. Note that adding __acquires() and __releases() for this doesn't help cure the warnings messages - something only commenting out both helps.
