sys/vfs/hammer2: Fail ioctl(HAMMER2IOC_GROWFS) if size > devvp size
Currently, ioctl(HAMMER2IOC_GROWFS) with growfs->size larger than
devvp size can destroy the volume. The ioctl needs to fail if size
> devvp size.
Note that hammer2(8) growfs directive always uses growfs->size == 0,
meaning the volume is always expanded to its devvp size.
