It was reported that grub mangles the kernel cmdline. It turns
acpi_cpufreq.dyndbg="file drivers/cpufreq/acpi-cpufreq.c +mpf"
into
"acpi_cpufreq.dyndbg=file drivers/cpufreq/acpi-cpufreq.c +mpf"
However, even though we could blame grub for doing that, the kernel
happily accepts and re-quotes it when the module is built-in.
So, it's better if kmod also understands it this way and does the same.
Here we basically add additional code to un-mangle it, moving the quote
in way that is acceptable to pass through init_module(). Note that the
interface [f]init_module() gives us mandates the quote to be part of the
value: the module name is not passed and the options are separated by
space.
