Fix an obscure fencepost error in GBDE's sector mapping code:
...
For certain combinations of sectorsize, mediasize and random numbers
(used to define the mapping), a multisector read or write would ignore
some subset of the sectors past the first sector in the request because
those sectors would be mapped past the end of the parent device, and
normal "end of media" truncation would zap that part of the request.
Rev 1.19+1.20 of g_bde_work.c added the check which should have alerted
me to this happening. This commit maps the request correctly and
adds KASSERTS to make sure things stay inside the parent device.
This does not change the on-disk layout of GBDE, there is no need to
backup/restore.

Fix a problem and slightly improve the ENOMEM handling:

Give up the entire bio as soon as we detect a problem.
When we detect a problem, give up the bio by contributing the
remainder with ENOMEM, rather than kicking the bio back right

If we failed on a non-first iteration we previously could end up
modifying fields in the bio after we delivered it. This could
account for memory corruption (none directly reported) on machines
with GBDE.
