V4L/DVB: s2250: Fix write_reg i2c address
The kernel i2c model uses right-aligned 7-bit i2c addresses, but the
2250 firmware uses an 8-bit address in the usb vendor request. A
previous patch by Jean Delvare shifted the i2c addresses 1 bit to the
right, and this patch fixes the write_reg function to shift it back
before sending the vendor request.
