[PATCH] lguest: clean up some l"references .init.text" warnings

[Rusty Russell]

Thanks to Andrew for pointing these out.

This patch moves the parvirtprobe section into .init.data: it's only
used in very very early boot, and for similar reasons, puts
lguest_maybe_init and lguest_memory_setup in init.text.

As well as fixing some warnings, this frees up a tiny bit more memory.
