[PATCH 05/11] UAPI: coda: Don't use internal kernel structs in UAPI

[David Howells]

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.
