Increase si2168 cmd execute timeout to prevent firmware load failures. Tests
shows it takes up to 52ms to load the 'dvb-demod-si2168-a30-01.fw' firmware.
Increase timeout to a safe value of 70ms.

Patch for stable 3.16+

That patch is already applied to master as commit 551c33e729f654ecfaed00ad399f5d2a631b72cb
There was some mistake and Cc stable tag I added to patchwork [1] was lost.
