[PPP]: Fix output buffer size in ppp_decompress_frame().
This patch addresses the issue with "osize too small" errors in mppe encryption. The patch fixes the issue with wrong output buffer size being passed to ppp decompression routine. -------------------- As pointed out by Suresh Mahalingam, the issue addressed by ppp-fix-osize-too-small-errors-when-decoding patch is not fully resolved yet. The size of allocated output buffer is correct, however it size passed to ppp->rcomp->decompress in ppp_generic.c if wrong. The patch fixes that. -------------------- Signed-off-by: Konstantin Sharlaimov <konstantin.sharlaimov@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
