Jason Gunthorpe b16de8b9e7 RDMA: Handle the return code from dma_resv_wait_timeout() properly 
ib_umem_dmabuf_map_pages() returns 0 on success and -ERRNO on failure.

dma_resv_wait_timeout() uses a different scheme:

 * Returns -ERESTARTSYS if interrupted, 0 if the wait timed out, or
 * greater than zero on success.

This results in ib_umem_dmabuf_map_pages() being non-functional as a
positive return will be understood to be an error by drivers.

Fixes: f30bceab16 ("RDMA: use dma_resv_wait() instead of extracting the fence")
