V4L/DVB (5573): Pvrusb2: kill unnecessary attribute->owner

sysfs is now completely out of driver/module lifetime game.

After deletion, a sysfs node doesn't access anything outside sysfs 
proper, so there's no reason to hold onto the attribute owners.

Note that often the wrong modules were accounted for as owners leading 
to accessing removed modules. 

This patch kills now unnecessary attribute->owner.  

Note that with this change, userland holding a sysfs node does not 
prevent the backing module from being unloaded. 

For more info regarding lifetime rule cleanup, please read the following
