    kldxref: Appease a Coverity warning
    
    While parsing .dynamic, nsym is set when parsing the symbol table from
    .dynsym.  That parsing also sets ef->ef_symtab to a non-NULL value.
    The value of nsym isn't validated until after a check for
    ef->ef_symtab being NULL, so nsym always has a valid value when it is
    read.  However, that chain of events is a bit much for static analysis
    to follow, so initialize nsym to 0 before parsing sections to quiet
    the warning.
