    protocol/server: Fix memory corruption during client-table-expand.
    
    gf_client_clienttable_expand frees up old entries after expanding. So,
    cliententry should be reassigned to a free slot in new array of
    cliententries. Earlier it used to point to a slot in oldentries
    resulting in a use-after-free bug.
    
    Thanks to Pranith for the assistance provided.

Client crash was because of glibc issue tracked by bz 1027101 and bz 1305406.
