math/bits: remove named return in TrailingZeros16
TrailingZeros16 is the only one of the TrailingZeros functions with a
named return value in the signature. This creates a sligthly
unpleasant effect in the godoc listing:
func TrailingZeros(x uint) int
func TrailingZeros16(x uint16) (n int)
func TrailingZeros32(x uint32) int
func TrailingZeros64(x uint64) int
func TrailingZeros8(x uint8) int
Since the named return value is not even used, remove it.
