The if statement that compares msgs[i].len != 3 is always false because
it is in a code block where msg[i].len is equal to 3. The check is
redundant and can be removed.

As detected by cppcheck static analysis:
drivers/media/usb/go7007/go7007-i2c.c:168:20: warning: Opposite inner
'if' condition leads to a dead code block. [oppositeInnerCondition]

Fixes: 866b8695d67e ("Staging: add the go7007 video driver")
