[PATCH v2] staging: pi433: Fix rf69_set_tx_cfg() logic

[Sidong Yang]

Moved code to configure sync to where check enable_sync option before.
There is no need to check enable_sync twice. Configuring sync should be
executed immediately after enabling sync.

v2: remove obvious comment. reordered size/value/enable sync functions.
