patch for wrong ERP-OFDM PLCP preamble and header values

ERP-OFDM of IEEE 802.11g defines a PLCP preamble duration of 16 microseconds and a PLCP header duration of 4 microseconds. However, those two values are inverted in ns-3. 

I attached a patch for this bug. Note that it doesn't change total TX time, but it correctly follows the standard.
