The size and layout of internal kernel structures may not be relied
upon outside of the kernel and may even change in a containerised
environment if a container image is frozen and shifted to another
machine.

Excise these from Coda's upc_req struct.

...

This structure should not have been exposed to userspace in the first
place: it's unusable by userspace as it is. It was incorrect to have it
outside of #ifdef __KERNEL__ before commit 607ca46e97a1b ... 

...

So the structure can be moved back to <linux/coda_psdev.h>.

I found a year old patch that clearly fell through the cracks that
fixes this exact thing.
