Subject: [PATCH] octeontx2-af: Change block parameter to const pointer in get_lf_str_list

Convert struct rvu_block block to const struct rvu_block *block in
get_lf_str_list() function parameter. This improves efficiency by
avoiding structure copying and reflects the function's read-only
access to block.

Fixes: e77bcdd1f639 (octeontx2-af: Display all enabled PF VF rsrc_alloc entries.)
