Mikhail Zaslonko f65c35d333 lib/zlib: DFLTCC always switch to software inflate for Z_PACKET_FLUSH option 
Since hardware inflate does not support Z_PACKET_FLUSH option (used
exclusively by kernel PPP driver), always switch to software like we
already do for Z_BLOCK flush option.  Without this patch, PPP might get
Z_DATA_ERROR return code from zlib_inflate() and disable zlib compression
for the packets.
