RDMA/hfi1: Remove use of kmap()
kmap() is being deprecated and will break uses of device dax after PKS protection is introduced.[1] The kmap() used in sdma does not need to be global. Use the new kmap_local_page() which works with PKS and may provide better performance for this thread local mapping anyway.
