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.

on entering.  Replace RVAL_IOCTL_PARSED with RVAL_IOCTL_DECODED
on exiting.
