[for-next PATCH 1/1] RDMA/rxe: sgt_append from ib_umem_get is not highmem

[Zhu Yanjun <yanjun.zhu@intel.com>]

From: Zhu Yanjun <yanjun.zhu@linux.dev>

In ib_umem_get, sgt_append is allocated from the function
sg_alloc_append_table_from_pages. And it is not from highmem.

As such, the return value of page_address will not be NULL.
