[PATCH v2 2/3] staging: pi433: change order in which driver config the rf69 chip

[Paulo Miguel Almeida]

There is an explicit dependency between modulation and bit rate
configurations. To ensure proper validation of input value for the
set_bit_rate routine, we must ensure that modulation has been set
before.

This patch ensures that set_modulation is always called before
set_bit_rate for both RX and TX routines
