videobuf functions at close() method already locks videobuf. It makes no sense
to keep the locking at empress close() method.
There is also a lock at open() method. I'm not sure if it is safe to remove the
locking there.

Improved display of still pictures (VIDEO_STILLPICTURE ioctl).
Ensure that both fields are displayed for progressive frames.
Thanks to Reinhard Nissl and Klaus Schmidinger for finding out
that the FREEZE command does this.

These two lines should indeed better be inside the if statement.

tuner_list can become static - and it's anyway a way too generic name
for a global variable - see commit b00ef4b8d8
for a completely different global variable of the same name I just made
static...

I updated the radio-si470x driver another time. Here are the commented history entries:
- number of seek_retries changed to tune_timeout
The last versions checked for the end of frequency tuning by polling a si470x register.
Therefore polling depended on the usb utilization.
This was changed to have a constant timeout now.
- fixed problem with incomplete tune operations by own buffers
The last version used a shared buffer to assembly the USB HID reports.
It sometimes happened, that multiple functions were modifing this buffer simultanuously.
When sending such reports, the hardware returned USB stalls (-EPIPE).
Now buffers of the correct size (smaller than before) are allocated as local variables.
- optimization of variables
The size of some variables has been reduced to allow the compiler to generate more optimized code.
- improved error logging
At some important location, error checking was improved.
Especially the usb transfers to access si470x registers and the tuning functions were modified.
