A recent patch attempted to enable more efficient memory usage by using
only 2kB descriptors for jumbo frames. The method used to implement this
has since been commented upon as "illegal" and in recent kernels even
causes a BUG when receiving ip fragments while using jumbo frames.
This patch simply goes back to the way things were. We expect some
complaints due to order 3 allocations failing to come back due to this
change.

- change interface of the reset functions from Scsi_Cmnd to Scsi_Host.
- add functions with the original interface and rename the new
functions to reflect the new interface.
- call these from the pcmcia driver, thereby avoiding the need to
construct a (broken) Scsi_Cmnd from a Scsi_Host.
- just run the bh if the interrupt is from the controller and if so
ensure that it's only called once per interrupt.

In order to use the new execute_in_process_context() API, you have to
provide it with the work storage, which I do in SCSI in scsi_device and
scsi_target, but which also means that we can no longer queue up the
target reaps, so instead I moved the target to a state model which
allows target_alloc to detect if we've received a dying target and wait
for it to be gone. Hopefully, this should also solve the target
namespace race.

When the locking was changed in the eh code ips_eh_reset was changed
so that it was a wraper around __ips_eh_reset and all ips_eh_reset
does is grab the host lock and then calls __ips_eh_reset.
In the queuecommand, ips_queue is called with the host_lock held so if
it calls ips_eh_reset we will have a problem. This patch just has
ips_queue call __ips_eh_reset.
Patch is only compile tested. I do not have the HW.
