[PATCH v4 76/79] coda_psdev.h: move upc_req definition from uapi to kernel side headers

[Mikko Rapeli <mikko.rapeli@iki.fi>]

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@cs.cmu.edu> on lkml message
<20150531111913.GA23377@cs.cmu.edu>.

Fixes these include/uapi/linux/coda_psdev.h compilation errors in userspace:

./linux/coda_psdev.h:12:19: error: field ‘uc_chain’ has incomplete type
  struct list_head    uc_chain;
                   ^
./linux/coda_psdev.h:13:2: error: unknown type name ‘caddr_t’
  caddr_t             uc_data;
  ^
./linux/coda_psdev.h:14:2: error: unknown type name ‘u_short’
  u_short             uc_flags;
  ^
./linux/coda_psdev.h:15:2: error: unknown type name ‘u_short’
  u_short             uc_inSize;  /* Size is at most 5000 bytes */
  ^
./linux/coda_psdev.h:16:2: error: unknown type name ‘u_short’
  u_short             uc_outSize;
  ^
./linux/coda_psdev.h:17:2: error: unknown type name ‘u_short’
  u_short             uc_opcode;  /* copied from data to save lookup */
  ^
./linux/coda_psdev.h:19:2: error: unknown type name ‘wait_queue_head_t’
  wait_queue_head_t   uc_sleep;   /* process' wait queue */
  ^
