Historically, various parameter-handling code kept pointers into
module::args, most notably the charp support. However, in 2009,
commit e180a6b7759a ("param: fix charp parameters set via sysfs") changed
charp parameters to kstrdup() the input string as well. As a result,
module::args now mostly wastes memory.Reviewing all kernel_param_ops and module_param_call instances shows that the last code still relying on module::args remaining valid for the module's lifetime is simdisk_param_ops_filename. Update it to use kstrdup() and then remove module::args.
