Fix the following warnings reported in radio-bcm2048.c:

WARNING: else is not generally useful after a break or return
374: FILE: radio-bcm2048.c:374:
+		return 0;
+	} else {

2601: FILE: radio-bcm2048.c:2601:

The following error was left since it seems to be a false positive:

ERROR: Macros with complex values should be enclosed in parenthesis
+#define DEFINE_SYSFS_PROPERTY(prop, signal, size, mask, check)		\
+property_write(prop, signal size, mask, check)				\
+property_read(prop, size, mask)
