[PATCHv2 wpan-next 4/6] at86rf230: remove unnecessary tx state change

[Alexander Aring <alex.aring@gmail.com>]

All supported transceivers can do a valid state change from TRX_OFF to
AACK_ON. This patach removes the state change chain from TRX_OFF ->
TX_ON -> AACK_ON instead we doing a directly state change from TRX_OFF
to AACK_ON.
