Subject: [PATCH] ppp: ppp_generic.c initialize flen before it get used


When while loop runs first time flen is used uninitialized for nfree <= 0

This also fixed compilation warning :
  CC [M]  drivers/net/ppp_generic.o
drivers/net/ppp_generic.c: In function ‘ppp_mp_explode’:
drivers/net/ppp_generic.c:1314: warning: ‘flen’ may be used uninitialized in this function
