[U-Boot] [PATCH] zlib.c: avoid build conflicts for cradle board

[Wolfgang Denk]

Commit dce3d79710 updated the zlib code to v0.95; this caused
conflicts when building for the "cradle" board, because the (pretty
generic) preprocessor variable "OFF" was used in multiple files.
Make sure to avoid further conflicts by #undef'ing it in zlib.c
before redefining it.
