selftests/bpf: Fix error compiling test_lru_map.c



[ Upstream commit cacf2a5a78cd1f5f616eae043ebc6f024104b721 ]

Although the post-increment in macro 'CPU_SET(next++, &cpuset)' seems safe,
the sequencing can raise compile errors, so move the increment outside the
macro. This avoids an error seen using gcc 12.3.0 for mips64el/musl-libc:

  In file included from test_lru_map.c:11:
  test_lru_map.c: In function 'sched_next_online':
  test_lru_map.c:129:29: error: operation on 'next' may be undefined [-Werror=sequence-point]
    129 |                 CPU_SET(next++, &cpuset);
        |                             ^
  cc1: all warnings being treated as errors
