PPP: Fix shadowing of global declaration

Browse Source 
Older compilers (GCC 4.6) don't like variables with the same name as
global functions:

lwip/src/netif/ppp/lcp.c: In function 'lcp_received_echo_reply':
lwip/src/netif/ppp/lcp.c:2685:11: error: declaration of 'magic' shadows a global declaration [-Werror=shadow]
lwip/src/include/netif/ppp/magic.h:101:7: error: shadowed declaration is here [-Werror=shadow]

magic.h contains a function named magic(), so rename the variable.
