Rémi Verschelde 6d16f2f053 Fix error macro calls not ending with semicolon
It's not necessary, but the vast majority of calls of error macros
do have an ending semicolon, so it's best to be consistent.
Most WARN_DEPRECATED calls did *not* have a semicolon, but there's
no reason for them to be treated differently.
