atm: zatm: Fix empty body Clang warnings
Clang warns: drivers/atm/zatm.c:513:7: error: while loop has empty body [-Werror,-Wempty-body] zwait; ^ drivers/atm/zatm.c:513:7: note: put the semicolon on a separate line to silence this warning Get rid of this warning by using an empty do-while loop. While we're at it, add parentheses to make it clear that this is a function-like macro.
