serial: msm_geni_serial: Handle Rx EOT & DMA_DONE after DMA Reset

Upon DMA reset dma_status is cleared, but if Rx EOT and
DMA_DONE bits are still set corresponding data is not
received from rx fifo. This scenario is encountered when
there was a cancel, abort, fsm reset failure.

Handle Rx EOT & DMA_DONE if set after DMA Reset.
