mac80211: move tx crypto decision
This patch moves the decision making about whether a frame is encrypted
with a certain algorithm up into the TX handlers rather than having it
in the crypto algorithm implementation.
This fixes a problem with the radiotap injection code where injecting
a non-data packet and requesting encryption could end up asking the
driver to encrypt a packet without giving it a key.
