Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct mlx5_fc_bulk. Cc: Saeed Mahameed <saeedm@xxxxxxxxxx> Cc: Leon Romanovsky <leon@xxxxxxxxxx> Cc: "David S.
