[PATCH v2 1/2] spi: geni-qcom: Fix incorrect free_irq() sequence

[Jinjie Ruan <ruanjinjie@xxxxxxxxxx>]

In spi_geni_remove(), the IRQ will still remain and it's interrupt handler
may use the dma channel after release dma channel and before free irq,
which is not secure, fix it.

Fixes: b59c122484ec ("spi: spi-geni-qcom: Add support for GPI dma")
