commonlib: Fix issues with { } and else

Fix the following errors and warning detected by checkpatch.pl:

ERROR: open brace '{' following struct go on the same line
ERROR: else should follow close brace '}'
WARNING: else is not generally useful after a break or return

False positives are detected for the following checkpatch.pl error.
ERROR: that open brace { should be on the previous line
These false positives are in cbfs.c for two function definitions.

TEST=Build and run Galileo Gen2
