block: sed-opal: keyring support for SED keys

Extend the SED block driver so it can alternatively
obtain a key from a sed-opal kernel keyring. The SED
ioctls will indicate the source of the key, either
directly in the ioctl data or from the keyring.

This allows the use of SED commands in scripts such as
udev scripts so that drives may be automatically unlocked
as they become available.
