Fix build errors when ZLIB_INFLATE=m and ZLIB_DEFLATE=m
and ZLIB_DFLTCC=y by exporting the 2 needed symbols in
dfltcc_inflate.c.
Fixes these build errors:
ERROR: modpost: "dfltcc_inflate" [lib/zlib_inflate/zlib_inflate.ko] undefined!
ERROR: modpost: "dfltcc_can_inflate" [lib/zlib_inflate/zlib_inflate.ko]
undefined!
Fixes: 126196100063 ("lib/zlib: add s390 hardware support for kernel
zlib_inflate")
