USB: serial: whiteheat: fix line-speed endianness

commit 84968291d7924261c6a0624b9a72f952398e258b upstream.

Add missing endianness conversion when setting the line speed so that
this driver might work also on big-endian machines.

Also use an unsigned format specifier in the corresponding debug
message.
