Subject: [PATCH] staging: lustre: constify cl_lock_operations

cl_lock_operations are not supposed to change at runtime.
cl_lock_slice_add is working with const cl_lock_operations.
So mark the non-const cl_lock_operations structs as const.

Someone else already sent this same patch in, and it's already applied
in my tree :(
