cdc-wdm endianness fixes
* wMaxPacketSize is le16; copying it to a field of local structure and then
using that field as host-endian (size of object to be allocated) is broken.
* bMaxPacketSize0 is 8-bit; feeding it to le16_to_cpu() is bogus and since the
result is used as host-endian, it's not even misspelled cpu_to_le16().
