Konstantin Sharlaimov 606f585e36 [PPP_MPPE]: Fix "osize too small" check.
Prevent mppe_decompress() from generating "osize too small" errors when
checking for output buffer size.  When receiving a packet of mru size the
output buffer for decrypted data is 1 byte too small since
mppe_decompress() tries to account for possible PFC, however later in code
it is assumed no PFC.

Adjusting the check prevented these errors from occurring.
