Re: [PATCH] lib/zlib_inflate/inffast: Check config in C to avoid unused function warning

Building Linux for ppc64le with Ubuntu clang version 12.0.0-3ubuntu1~21.04.1
shows the warning below.

     arch/powerpc/boot/inffast.c:20:1: warning: unused function 'get_unaligned16' [-Wunused-function]
     get_unaligned16(const unsigned short *p)
     ^
     1 warning generated.

Fix it, by moving the check from the preprocessor to C, so the compiler
sees the use.
