staging: pi433: rf69.c style fix - trailing statements

This patch fixes the following checkpatch.pl error:

ERROR: trailing statements should be on next line

in rf69.c file as requested by TODO file.

Note:
ERROR: spaces required around that '=' (ctx:VxV)
remains valid here and is going to be fixed by the next patch in set.

Additionally some style warnings remain valid here and could be fixed by
another patch.
