cpuidle: teo: Drop local variable prev_intercept_idx

Local variable prev_intercept_idx in teo_select() is redundant because
it cannot be 0 when candidate state index is 0.

The prev_intercept_idx value is the index of the deepest enabled idle
state, so if it is 0, state 0 is the deepest enabled idle state, in
which case it must be the only enabled idle state, but then teo_select()
would have returned early before initializing prev_intercept_idx.

Thus prev_intercept_idx must be nonzero and the check of it against 0
always passes, so it can be dropped altogether.

No intentional functional impact.
