[PATCH v4 2/3] spi: geni-qcom: Fix incorrect free_irq() sequence

[Jinjie Ruan <ruanjinjie@xxxxxxxxxx>]

In spi_geni_remove(), the free_irq() sequence is different from that
on the probe error path. And 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")
