spi: spi-qcom-qspi: Ignore disabled interrupts' status in isr
During FIFO/DMA modes dynamic switching, only corresponding interrupts are
enabled. However its possible that FIFO related interrupt status registers
get set during DMA mode. For example WR_FIFO_EMPTY bit is set during DMA
TX.
Ignore such status bits so that they don't trip unwanted operations.
