media: dib9000: delete some unused broken code
The dib9000_remove_slave_frontend() function isn't used.
I was reviewing it because my static checker claims it writes one
element beyond the end of the array. That's a false positive. What it
actually does is, if there are two or more front ends, then it prints a
debug message to say that it removed the first one, stored in
state->fe[1], and then it "removes" (scare quotes on purpose) the second
one, stored in state->fe[2]. Deleting a front end from the middle is
not really supported and breaks code like dib9000_release() which
assumes the first NULL front end marks the end of the list.
