[PATCH] mm/memblock.c: remove unnecessary always-true comparison

[Richard Leitner]

Comparing an u64 variable to >= 0 returns always true and can therefore
be removed. This issue was detected using the -Wtype-limits gcc flag.

This patch fixes following type-limits warning:

mm/memblock.c: In function â__next_reserved_mem_regionâ:
mm/memblock.c:843:11: warning: comparison of unsigned expression >= 0 is
always true [-Wtype-limits]
  if (*idx >= 0 && *idx < type->cnt) {
