    net: ax25: fix information leak to userland

    Sometimes ax25_getname() doesn't initialize all members of fsa_digipeater
    field of fsa struct, also the struct has padding bytes between
    sax25_call and sax25_ndigis fields. This structure is then copied to
    userland. It leads to leaking of contents of kernel stack memory.
