RDMA/umem: Constify struct dma_buf_attach_ops
'struct dma_buf_attach_ops' are not modified in this driver.
Constifying these structures moves some data to a read-only section, so
increases overall security, especially when the structure holds some
function pointers.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
10300 1216 0 11516 2cfc drivers/infiniband/core/umem_dmabuf.o
After:
=====
text data bss dec hex filename
10428 1088 0 11516 2cfc drivers/infiniband/core/umem_dmabuf.o
