Patch to add method WifiPhy::IsValidTxVector

The 802.11ac standard has several MCS values that are listed as "Not valid".
A list of invalid combinations can be found here http://chimera.labs.oreilly.com/books/1234000001739/ch02.html#table-phy-invalid-mcs

This methods check for the validity of WifiTxVector.
It is necessary for rate control algorithms to avoid this invalid combinations.

I did not check the combinations in detail, but it looks ok.
