fsldma: bug fix for dma suspend
During the suspend process, DMA channels are suspended one by one, if one
channel cannot be suspended, all the former channels which have been suspended
should be restored, i.e. mark the pm_state as running, and release the spin
locks aquired.
This patch adds the "pm_state = RUNNING" which was omitted in the original
suspend patch.
