disp: msm: sde: allow spec fence signaled with PENDING_ERROR as non fatal

Browse Source 
In concurrent display usecases, dma_fence_array signaled op
can be called early which sets SIGNALED_BIT on spec fence, but
irq_dma_fence_array_work is not scheduled yet which clears the
PENDING_ERROR in dma_fence. Add changes to treat pending_error
with signaled cases as non fatal.
