media: dw2102: fix a potential buffer overflow

As pointed by smatch:
 drivers/media/usb/dvb-usb/dw2102.c:802 su3000_i2c_transfer() error: __builtin_memcpy() '&state->data[4]' too small (64 vs 67)

That seemss to be due to a wrong copy-and-paste.

Fixes: 0e148a522b84 ("media: dw2102: Don't translate i2c read into write")
