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.
