ipvs: fix type warning in do_div() on 32 bit
32 bit platforms without 64bit div generate the following warning: net/netfilter/ipvs/ip_vs_est.c: In function 'ip_vs_est_calc_limits': include/asm-generic/div64.h:222:35: warning: comparison of distinct pointer types lacks a cast 222 | (void)(((typeof((n)) *)0) == ((uint64_t *)0)); \ | ^~ net/netfilter/ipvs/ip_vs_est.c:694:17: note: in expansion of macro 'do_div' 694 | do_div(val, loops); | ^~~~~~ include/asm-generic/div64.h:222:35: warning: comparison of distinct pointer types lacks a cast 222 | (void)(((typeof((n)) *)0) == ((uint64_t *)0)); \ | ^~ net/netfilter/ipvs/ip_vs_est.c:700:33: note: in expansion of macro 'do_div' 700 | do_div(val, min_est); | ^~~~~~ first argument of do_div() should be unsigned. We can't just cast as do_div() updates it as well, so we need an lval. Make val unsigned in the first place, all paths check that the value they assign to this variables are non-negative already.
