[media] saa7134: avoid complex macro warnings
The debug macros are not properly defined, as they generate warnings
like:
ERROR: Macros with complex values should be enclosed in parentheses
+#define core_dbg(fmt, arg...) if (core_debug) \
+ printk(KERN_DEBUG pr_fmt("core: " fmt), ## arg)
Use do { } while (0) for those macros.
