The second argument of rtl8188e_set_FwMediaStatus_cmd() needs to be in CPU
order, not little-endian; however, when it uses that value to call
FillH2CCmd_88E() the parameter must be in little-endian order as that
value will be sent to the firmware. Note that the conversion from LE to CPU
order was le16_to_cpu() rather than the correct cpu_to_le16.

The definition of FillH2CCmd_88E() is revised, and the proper conversion
routine is used.

Note that the original code performed one byte swap on the secong argument
of FillH2CCmd_88E(), and got the correct answer even though the semantics
were very wrong.
