[PATCH] ppp: Fix ppp_deflate issues with recent zlib_inflate changes
The last zlib_inflate update broke certain corner cases for ppp_deflate
decompression handling. This patch fixes some logic to make things work
properly again. Users other than ppp_deflate (the only Z_PACKET_FLUSH
user) should be unaffected.
Fixes bug 8405 (confirmed by Stefan)
