[PATCH] mm/zsmalloc: fix build warning from lkp testing

[alexs]

From: "Alex Shi (Tencent)" <alexs@xxxxxxxxxx>

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@xxxxxxxxx>
Closes: https://lore.kernel.org/oe-kbuild-all/202407052102.qbT7nLMK-lkp@xxxxxxxxx/
