[PATCH 0/3] Fix streaming on/off logic

[Mauro Carvalho Chehab]

As discussed on:
	https://github.com/hselasky/webcamd/issues/16

the dib0700 had a regression on Kernel 2.6.39. Such regression didn't
affect most devices, in practice, as it seems to happen only under
certain circunstances. 

Michael came up with a solution for the issue (already submitted to
the ML) but let's take the opportunity to do a cleanup, as the resulting
code was still touching both adapters when an stream off command
was issued to one adapter, turning on the other one.

After the change, each adapter is idependently controlled by
a separate bit, as can be shown when its debug message 
is turned on (tested on a dual-adapter device: Hauppauge
WinTV Nova TD):

[608855.124780] adapter 1, streaming ON: 0f 10 12
[608868.189827] adapter 0, streaming ON: 0f 10 13
[608879.584330] adapter 1, streaming OFF: 0f 00 11
[608887.014772] adapter 0, streaming OFF: 0f 00 10
