spi: geni-qcom: Check DMA interrupts early in ISR
The current interrupt handler only checks the GENI main IRQ status
(m_irq) before deciding to return IRQ_NONE. This can lead to spurious
IRQ_NONE returns when DMA interrupts are pending but m_irq is zero.
Move the DMA TX/RX status register reads to the beginning of the ISR,
right after reading m_irq. Update the early return condition to check
all three status registers (m_irq, dma_tx_status, dma_rx_status) before
returning IRQ_NONE.
