This pushes the BKL down into the driver.  Based on a patch by Alan Cox.

We need to do it this way for now as the inode parameter of viotap_ioctl
is used internally as a flag.  We should do a further cleanup patch.

The saa7134 driver uses a (non-atomic) variable in an attempt to
only allow one opener of the device (how it deals with sending
the fd over unix sockets I don't know).

Unfortunately, the release function first decrements this variable,
and THEN goes on to disable more of the device. This allows for
a race where another opener of the device comes in after the decrement of
the variable, configures the hardware just to then see the hardware
be disabled by the rest of the release function.

This patch makes the release function use the same lock as the open
function to protect the hardware as well as the variable (which now
at least has some locking to protect it).

reports from Yuri Warczynski <Yuri.Warczynski@gmail.com> and
Brian Hope <brian@hopefamily.info> and enable the card entry.  The tuner reset
GPIO pin is likely incorrect as the tuner firmware cannot be reloaded without a
reboot.  It is likely the audio routing is done via GPIO which is not
implemented yet, as users report audio doesn't work for some inputs.
