RDMA/mlx5: Constify struct ib_frmr_pool_ops and dma_buf_attach_ops

Browse source

'struct ib_frmr_pool_ops' and '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.

While at it, change a '1' into a 'true' into the mlx5_ib_dmabuf_attach_ops
structure. The 'allow_peer2peer' field is a bool and other usages of
'struct dma_buf_attach_ops' prefer using true/false.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  77631	  10392	    320	  88343	  15917	drivers/infiniband/hw/mlx5/mr.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  77759	  10264	    320	  88343	  15917	drivers/infiniband/hw/mlx5/mr.o
