fscrypt-crypt-util: refactor get_key_and_iv()

Split get_key_and_iv() into two distinct parts: (1) deriving the key and
(2) generating the IV.  Also, check for the presence of needed options
just before they are used rather than doing it all up-front.

These changes should make this code much easier to understand.
