Pointer arthemitic with 'void * addr' and 'ulong dest_alignment' triggers following warning:

mremap_test.c:1035:31: warning: pointer comparison always evaluates to false [-Wtautological-compare] 1035 | if (addr + c.dest_alignment < addr) { | ^

this warning is raised from clang version 20.1.8 (Fedora 20.1.8-4.fc42).

use 'void *tmp_addr' to do the pointer arthemitic.
