[SCSI] SCSI core kmalloc2kzalloc

Has an incorrect piece in sr_ioctl.c; it changes buffer from kmalloc
to kzalloc, but then removes the clearing of the stack variable struct
packet_command.  This, in turn leaves rubbish in the sense pointer

Ok, so here is my first take at satisfying this request.
Be warned, that beyond compiling, and checking that the new module
doesn't immediately blow up, there hasn't yet been a lot of testing.

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

functions) where we need to guarantee process context, but (given the
place where the last reference was released) we cannot guarantee this.

This API gets around the issue by executing the function directly if
the caller has process context, but scheduling a workqueue to execute
in process context if the caller doesn't have it.
