monitor: Fix out-of-bound read in print_le_states

Accessing le_states_desc_table array with value 15 can cause
out-of-bound read because current size of array is 14.

Currently this cannot lead to any problems becase we do no have such
state in le_states_comb_table but this could be changed in future and
raise described problem.
