vfs: add kill_sb callback to vfs_fs_type_t for filesystem cleanup (P2.3)

- Add kill_sb function pointer to vfs_fs_type_t
- Update vfs_umount_nolock to call fstype->kill_sb instead of direct fat_umount/ext2_umount
- Implement fat_kill_sb and ext2_kill_sb callbacks in init.c
- Callbacks call filesystem-specific umount and free superblock
