From: Alex Shi <alexs@kernel.org>

LKP reported the following warning w/o CONFIG_DEBUG_VM:
mm/zsmalloc.c:471:12: warning: function 'is_first_zpdesc' is not
needed and will not be emitted [-Wunneeded-internal-declaration]
To remove this warning, better to incline the function is_first_zpdesc

Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202407052102.qbT7nLMK-lkp@intel.com/
