spi: img-spfi: don't disable runtime PM on DMA deferred probe

Browse source

When dma_request_chan() returns -EPROBE_DEFER, the error path jumps to
disable_pm and calls pm_runtime_disable() even though pm_runtime_enable()
was never called, leaving disable_depth unbalanced and the device
permanently PM-disabled.

Route the defer path through free_dma to skip pm_runtime_disable().
