Fedora users complain that passing "nousbstorage" to the installer causes
the rest of the USB support to disappear. The installer uses kernel command
line as a way to pass options through Syslinux. The problem stems from the
use of strncmp() in obsolete_checksetup().
I used __module_param_call() instead of module_param because I wanted to
preserve the old syntax in grub.conf, and it's the only macro which allows
to remove the prefix.
The fix is tested to accept the option "nousb" correctly now.
