fix[hal_rkdec]: Fix duplicate align on ver_stride in fbc mode

Browse Source 
When MPP_DEC_SET_FRAME_INFO configures fbc format with height not
16-aligned, vdpu_afbc_align_calc aligns height to 16 first. Then
mpp_sys_dec_buf_chk_proc adds 8 expand and aligns to 16 again,
causing ver_stride to be 24 larger than expected.

Use the existing ver_stride from frame if already set, to avoid
duplicate alignment.
