Simple filesystems such as ext2 or udf do not support delayed allocation. Thus they allocate data blocks for mmap writes only during writeback. This makes test generic/614 fail because it checks exactly whether the blocks for the write are reserved before writeback happens. Make the test depend on delayed allocation support.
