libkmod mishandles parameters re-quoted by grub2

Hi,

when one passes to the kernel a module parameter from grub2 such as:
  parport.dyndbg="file drivers/parport/ieee1284_ops.c +mpf"
the kernel receives:
  "parport.dyndbg=file drivers/parport/ieee1284_ops.c +mpf"
as grub2 handles quotes this way. It may be a bug in grub2, it was even tried to be fixed, but there is no all-cases-working fix yet:
  https://bugzilla.suse.com/show_bug.cgi?id=1181111#c10

The kernel parses the parameter correctly, though:
  parse_one: doing dyndbg params: parport.dyndbg='file drivers/parport/ieee1284_ops.c +mpf'

But libkmod doesn't. When parport is modprobe-d, this parameter is not passed to it.

kmod_config_parse_kcmdline ignores the parameter as:
  if (is_quoted) {
    /* don't consider a module until closing quotes */

I am not sure how to fix this, can someone look into it and make the parser similar to kernel's?

thanks,
