errors if degree > deg_free (#1170)

Code
  recipe(~., data = mtcars) %>% step_spline_monotone(mpg, degree = 3, deg_free = 3,
    complete_set = TRUE) %>% prep()
Condition
  Error in `step_spline_monotone()`:
  Caused by error in `prep()`:
  ! `degree` (3) must be less than to `deg_free` (3) when `complete_set = FALSE`.

Code
  recipe(~., data = mtcars) %>% step_spline_monotone(mpg, degree = 4, deg_free = 3,
    complete_set = FALSE) %>% prep()
Condition
  Error in `step_spline_monotone()`:
  Caused by error in `prep()`:
  ! `degree` (4) must be less than or equal to `deg_free` (3) when `complete_set = TRUE`.

check_name() is used

Code
  prep(rec, training = dat)
Condition
  Error in `step_spline_monotone()`:
  Caused by error in `bake()`:
  ! Name collision occurred. The following variable names already exist:
