src: fix enum/integer mismatches

gcc 13 complains about type confusion:
cache.c:1178:5: warning: conflicting types for 'nft_cache_update' due to enum/integer mismatch;
have 'int(struct nft_ctx *, unsigned int,  struct list_head *, const struct nft_cache_filter *)' [-Wenum-int-mismatch]
cache.h:74:5: note: previous declaration of 'nft_cache_update' with type 'int(struct nft_ctx *, enum cmd_ops,  struct list_head *, const struct nft_cache_filter *)'

Same for:
rule.c:1915:13: warning: conflicting types for 'obj_type_name' due to enum/integer mismatch; have 'const char *(enum stmt_types)' [-Wenum-int-mismatch]
 1915 | const char *obj_type_name(enum stmt_types type)
      |             ^~~~~~~~~~~~~
expression.c:1543:24: warning: conflicting types for 'expr_ops_by_type' due to enum/integer mismatch; have 'const struct expr_ops *(uint32_t)' {aka 'const struct expr_ops *(unsigned int)'} [-Wenum-int-mismatch]
 1543 | const struct expr_ops *expr_ops_by_type(uint32_t value)
      |                        ^~~~~~~~~~~~~~~~

Convert to the stricter type (enum) where possible.
