Subject: uapi linux/coda_psdev.h: move upc_req definition from uapi to kernel side headers
Only users of upc_req in kernel side fs/coda/psdev.c and fs/coda/upcall.c
already include linux/coda_psdev.h.
Suggested by Jan Harkes <jaharkes@xxxxxxxxxx> on lkml message
<20150531111913.GA23377@xxxxxxxxxx>.
Fixes these include/uapi/linux/coda_psdev.h compilation errors in userspace:

struct list_head uc_chain;
^
