icp: add no_const for PaX Compat

Browse Source 
The constify plugin will automatically constify a class of types that contain
only function pointers. The icp structs fail to build if this is enabled with
the following error. The no_const attribute makes the plugin skip those
structs.

module/icp/spi/kcf_spi.c: In function ‘copy_ops_vector_v1’:
module/icp/spi/kcf_spi.c:61:16: error: assignment of read-only location ‘*dst_ops->cou.cou_v1.co_control_ops’
  *((dst)->ops) = *((src)->ops);
                ^
module/icp/spi/kcf_spi.c:74:2: note: in expansion of macro ‘KCF_SPI_COPY_OPS’
  KCF_SPI_COPY_OPS(src_ops, dst_ops, co_control_ops);
  ^
