f2fs: fix to enable missing ioctl interfaces in ->compat_ioctl
In 64-bit kernel f2fs can supports 32-bit ioctl system call by identifying encoded code which is converted from 32-bit one to 64-bit one in ->compat_ioctl. When we introduced new interfaces in ->ioctl, we forgot to enable them in ->compat_ioctl, so enable them for fixing.
