Before we free the opal structure we need to clean up any saved
locking ranges that the user had told us to unlock from a suspend.

Insted of bloating the containing structure with it all the time this
allocates struct opal_dev dynamically. Additionally this allows moving
the definition of struct opal_dev into sed-opal.c. For this a new
private data field is added to it that is passed to the send/receive
callback. After that a lot of internals can be made private as well.

When CONFIG_KASAN is enabled, compilation fails:
block/sed-opal.c: In function 'sed_ioctl':
block/sed-opal.c:2447:1: error: the frame size of 2256 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
Moved all the ioctl structures off the stack and dynamically allocate
using _IOC_SIZE()
Fixes: 455a7b238cd6 ("block: Add Sed-opal library")

This patch implements the necessary logic to bring an Opal
enabled drive out of a factory-enabled into a working
Opal state.
This patch set also enables logic to save a password to
be replayed during a resume from suspend.
