[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.
