Fix printf warning in libmpiwrap.c

libmpiwrap.c:1379:45: warning: format '%d' expects argument of type 'int',
but argument 5 has type 'MPI_Request' {aka 'struct ompi_request_t *'}

Unfortunately MPI_Request is an opaque type (we don't really know what
is in struct ompi_request_t) so we cannot simply print it as int. In
other places we print an MPI_Request as 0x%lx by casting it to an
unsigned long. Do the same here.
