[PATCH] libertas: store rssi as an int

"struct bss_descriptor" has nothing to do with hardware, 
otherwise you would see __le32 there. Using an "u8" saves us 
nothing, except we move all u8's at the end of the struct. But 
this would give us unaligned u8's and some processors have 
problems with that.
