Revert unnecessary zlib_inflate/inftrees.c fix
It turns out that empty distance code tables are not an error, and that a compressed block with only literals can validly have an empty table and should not be flagged as a data error. Some old versions of gzip had problems with this case, but it does not affect the zlib code in the kernel. Analysis and explanations thanks to Sergey Vlasov <vsu@altlinux.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
