[LR1121] Decrease PACKET_TO_TOCK_SLACK (ExpressLRS#2621)

* decrease PACKET_TO_TOCK_SLACK

Removes an unnecessary GetIrqStatus and optimises SetFrequencyReg order.  This saves 20us that can then be removed from SLACK and provides enough time for packets when using 2.4G 500Hz 1:2 TLM.

* reduce SLACK some more

* fix build errors
