rcu: Semicolon inside RCU_TRACE() for Tiny RCU
The current use of "RCU_TRACE(statement);" can cause odd bugs, especially where "statement" is a local-variable declaration, as it can leave a misplaced ";" in the source code. This commit therefore converts these to "RCU_TRACE(statement;)", which avoids the misplaced ";". Reported-by: NJosh Triplett <josh@joshtriplett.org> Signed-off-by: NPaul E.
