modpost: remove unneeded .symbol_white_list initializers
The ->symbol_white_list field is referenced in secref_whitelist(),
only when 'fromsec' is data_sections.
/* Check for pattern 2 */
if (match(tosec, init_exit_sections) &&
match(fromsec, data_sections) &&
match(fromsym, mismatch->symbol_white_list))
return 0;
If .fromsec is not data sections, the .symbol_white_list member is
not used by anyone.
