Documentation: media: gen-errors.rst: fix confusing ENOTTY description
The text is very, very old and predates /dev/mediaX devices, so the
reference to "media device" is today very confusing.
It also says that the ioctl is not supported by the driver, but a
driver may have multiple device nodes, some support a given ioctl,
and some don't.
Simplify the description: ENOTTY means that the ioctl is not supported
by the file descriptor.
