kABI: Fix kABI macros use COUNT_ARGS

deepin inclusion
category: bugfix

commit b229baa ("kernel.h: split out COUNT_ARGS() and CONCATENATE() to args.h")
move COUNT_ARGS to linux/args.h, it lead to make some headers not include it.
lead to strange build failed when use KABI_USE.
It can be reproduced in original rh_kabi.h(use centos 10) + upstream 6.6 in fwnode.h,
and commit 1dc05a2 ("device property: Replace custom implementation of COUNT_ARGS()")
include args.h, so it cannot be reproduced after v6.7 upstream.
