bpf: Fix warning in check_obj_size()

From: Hou Tao <houtao1@huawei.com>

Hi,

The patch set aims to fix the warning in check_obj_size() as reported by
lkp [1]. Patch #1 fixes the warning by selecting target cache for free
request through c->unit_size, so the unnecessary adjustment of
size_index and the checking in check_obj_size() can be removed. Patch #2
fixes the test failure in test_bpf_ma after applying patch #1.

Please see individual patches for more details. And comments are always
welcome.
