lib/zlib: DFLTCC support inflate with small window
There is no hardware control for DFLTCC window size. After this change,
software and hardware window formats no longer match: the software will
use wbits and wsize, and the hardware will use HB_BITS and HB_SIZE.
Since neither dictionary manipulation nor internal allocation functions
are relevant to kernel zlib and zlib_inflate_workspacesize() always use
MAX_WBITS for window size calculation, only dfltcc_can_inflate() and
dfltcc_inflate() functions are affected by this patch.
