When loading fields from packed structs, use get_unaligned_le16 and
get_unaligned_le32 instead of le16_to_cpu and le32_to_cpu.
This doesn't matter on x86, but it is important for some other CPUs.
Also, mark all packed structs as packed. Generally, any data structure
that comes over the wire from the WLAN firmware should be a packed struct.
