Marek Vasut fa847bb409 test: Wrap assert macros in ({ ... }) and fix missing semicolons 
Wrap the assert macros in ({ ... }) so they can be safely used both as
right side argument as well as in conditionals without curly brackets
around them. In the process, find a bunch of missing semicolons, fix
them.
