    imgact_elf: Unconditionally initialize a variable in a note handler
    
    In the sb == NULL case, we are computing the size of the note using a
    dummy sbuf drain handler which counts bytes and discards the contents of
    the buffer, so the fact that "structsize" is uninitialized doesn't
    matter.  But, the compiler may complain about this, so we might as well
    just initialize it unconditionally to silence the warning, as other
    handlers already do.
