target/arm: Correct VMOV_imm_dp handling of short vectors

Browse source 
Coverity points out (CID 1402195) that the loop in trans_VMOV_imm_dp()
that iterates over the destination registers in a short-vector VMOV
accidentally throws away the returned updated register number
from vfp_advance_dreg(). Add the missing assignment. (We got this
correct in trans_VMOV_imm_sp().)

Backports commit 89a11ff756410aecb87d2c774df6e45dbf4105c1 from qemu
