sheepdog driver should decide a write request is COW or not based on inode
object which is active when the write request is issued.
Example of wrong inode update path in the previous driver:
1. drier issues an ordinal write request to an existing object
2. user creates a snapshot of the VDI before the write request is completed
3. the respones for the request is RDONLY, because the VDI is already a snapshot
4. the driver reload an inode object of the new active VDI, then issues a write
request again
5. the second write request can be completed
6. driver decide the request is COW or not with the below conditional branch:
if (s->inode.data_vdi_id[idx] != s->inode.vdi_id) {
7. the ID of the written object and VID of the new active VDI is different, so
the driver updates data_vdi_id[idx] and writes inode object
8. the existing object cannot be seen by the new active VDI, it results object
leaking

This is an intermediate step to bring TCX in line with CG3.
Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
CC: Andreas Färber <afaerber@suse.de>
The case statements in the CG3 read and write register routines have a maximum
value of CG3_REG_SIZE, so if a value were written to this offset then it
would overflow the register array.
Currently this cannot be exploited since the MemoryRegion restricts accesses
to the range 0 ... CG3_REG_SIZE - 1, but it seems worth clarifying this for
future review and/or static analysis.

With SMAP, implicit kernel accesses from user mode always behave as
if AC=0. To do this, kernel mode is not anymore a separate MMU mode.
Instead, KERNEL_IDX is renamed to KSMAP_IDX and the kernel mode accessors
wrap KSMAP_IDX and KNOSMAP_IDX.
