fscrypt: new helper function - fscrypt_prepare_link()
Introduce a helper function which prepares to link an inode into a
possibly-encrypted directory. It handles setting up the target
directory's encryption key, then verifying that the link won't violate
the constraint that all files in an encrypted directory tree use the
same encryption policy.
