content_encoding: fix inflate_stream for no bytes available
- Don't call zlib's inflate() when avail_in stream bytes is 0.
This is a follow up to the parent commit 19e66e5. Prior to that change
libcurl's inflate_stream could call zlib's inflate even when no bytes
were available, causing inflate to return Z_BUF_ERROR, and then
inflate_stream would treat that as a hard error and return
CURLE_BAD_CONTENT_ENCODING.
According to the zlib FAQ, Z_BUF_ERROR is not fatal.
This bug would happen randomly since packet sizes are arbitrary. A test
of 10,000 transfers had 55 fail (ie 0.55%).
