codecparsers: h265: Fix the selection of Active Ref Pic Set

Browse source 
If short_term_ref_pic_set_sps_flag is FALSE, the ShortTermRefPicSet
structure is supposed to derive from slice header. Which means,
CurrRpsIdx is equal to num_short_term_ref_pic_sets. But the number
of refpicsets communicated via sps header is only num_short_term_ref_pic_sets - 1.
And we are using slice_header structure to reference the last entry, which is
ShortTermRefPicSet[num_short_term_ref_pic_sets].
