RDMA/qib: Remove deprecated kmap() call
kmap() has been deprecated in favor of the kmap_local_page() call.
kmap_local_page() is thread local.
In the sdma coalesce case the page allocated is potentially free'ed in a
different context through qib_sdma_get_complete() ->
qib_user_sdma_make_progress(). The use of kmap_local_page() is
inappropriate in this call path. However, the page is allocated using
GFP_KERNEL and will never be from highmem.
Remove the use of kmap calls and use page_address() in this case.
