[PATCH] Fix an endian bug in dbus properties.

[Sylvestre Gallon]

Hi,

Here is a patch to allow the use of Frequency and Signal DBus
properties for Big Endian targets.

I have tried NetworkManager on a powerpc target (BigEndian) and I find
that these properties does not work (always 100% for Signal and 0 for
Frequency). After some investigation I find that the bug come from an
endian problem in wpa_supplicant (u32 to u16 data loss).

Cheers,
