RDMA/umem: Add ib_umem_is_contiguous() stub for !CONFIG_INFINIBAND_USER_MEM

ib_umem_is_contiguous() is defined under #ifdef
CONFIG_INFINIBAND_USER_MEM, but the #else branch lacks a stub.

Add the missing inline to fix potential broken build.

Fixes: c897c2c8b8e8 ("RDMA/core: Add umem "is_contiguous" and "start_dma_addr" helpers")
