sgsnemu: Fix bad ptr during context deallocation

Browse Source 
Older commit switched pdp_t to have an array of 2 peers instead of
only one in order to accomodate for ipv4v6 contexts, which can have 2
addresses assigned. The usage of peer field was not updated in sgsnemu
accordingly, which means the wrong memory portion was being accessed.

Fixes: 2d6a69e69a ("Add support for IPv4v6 End User Addresses")
