net: ppp: access ppp->nextseq only if CONFIG_PPP_MULTILINK is defined
Commit d762d038497c9df51c19fcbe69b094b3bf8e5568 resets the counter holding the next sequence number for multilink PPP fragments to zero whenever the SC_MULTILINK flag is set. However, this counter only exists if CONFIG_PPP_MULTILINK is defined. Consequently, the new code has to be enclosed within #ifdef CONFIG_PPP_MULTILINK ... #endif.
