When we switched over from binder_ctl.h to binderfs.h we forgot to change
the include guards. It's minor but it's obviously correct.

We allow more then 255 binderfs binder devices to be created since there
are workloads that require more than that. If we use __u8 we'll overflow
after 255. So let's use a __u32.
Note that there's no released kernel with binderfs out there so this is
not a regression.
