Since commit acaab7335bd6 ("lib/zlib: remove outdated and incorrect
pre-increment optimization"), get_unaligned16() is only used when
!CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS.
Hence, make CC=clang W=1 warns:
lib/zlib_inflate/inffast.c:20:1:
warning: unused function 'get_unaligned16' [-Wunused-function]
Define get_unaligned16() only when it is actually used.
