Dmitry V. Levin d45d71be06 Imply RVAL_DECODED when RVAL_IOCTL_PARSED is returned on entering
Also, rename RVAL_IOCTL_PARSED to RVAL_IOCTL_DECODED as the latter
is a more suitable name.

* defs.h (RVAL_IOCTL_PARSED): Rename to RVAL_IOCTL_DECODED.
* ioctl.c (ioctl_decode): Update comment.
(SYS_FUNC(ioctl)): Replace RVAL_IOCTL_PARSED with RVAL_IOCTL_DECODED,
add convertation of RVAL_IOCTL_DECODED to RVAL_DECODED.
* block.c (block_ioctl): Replace RVAL_DECODED | RVAL_IOCTL_PARSED
with RVAL_IOCTL_DECODED on entering.  Replace RVAL_IOCTL_PARSED
with RVAL_IOCTL_DECODED on exiting.
* btrfs.c (btrfs_ioctl): Likewise.
* evdev.c: Likewise.
* file_ioctl.c: Likewise.
* fs_x_ioctl.c: Likewise.
* hdio.c: Likewise.
* loop.c: Likewise.
* mtd.c: Likewise.
* nsfs.c: Likewise.
* print_sg_req_info.c: Likewise.
* ptp.c: Likewise.
* rtc.c: Likewise.
* scsi.c: Likewise.
* sg_io_v3.c: Likewise.
* sg_io_v4.c: Likewise.
* sock.c: Likewise.
* term.c: Likewise.
* ubi.c: Likewise.
* userfaultfd.c: Likewise.
* dm.c (dm_known_ioctl): Return RVAL_IOCTL_DECODED on exiting and 0
on entering.  Replace RVAL_IOCTL_PARSED with RVAL_IOCTL_DECODED
on exiting.
* v4l2.c: Likewise.
