We free the struct ubootvarfs_inode::var as part of destroy_inode. In
case we have unlinked the U-Boot variable beforehand, we will end up
double-freeing. Set the member to NULL, so it's skipped in
destory_inode. We keep the free in destroy_inode, because that's still
needed for all the other inodes that aren't unlinked.
