    PPP: improve randomization of LCP magic number after power-up
    
    magic_init() is first time called from ppp_init(), which is called from
    lwip_init(). If system has no RTC, sys_jiffies() returns same value in
    this moment after every power-up or system reset. This value used in LCP
    magic number generation after ppp_connect(), which leads to same magic
    number after every restart. Subsequent magic_randomize() calls takes
    place in ppp_input(), after magic number generation.
    
    Call magic_randomize() somewhere near start of ppp_connect() (and
    ppp_listen()) as it might be called later at a random time.
