dmaengine: sf-pdma: apply proper spinlock flags in sf_pdma_prep_dma_memcpy()
The second parameter of spinlock_irq[save/restore] function is flags, which is the last input parameter of sf_pdma_prep_dma_memcpy(). So declare local variable 'iflags' to be used as the second parameter of spinlock_irq[save/restore] function.
