spi: spi-ti-qspi: Suspend the queue before removing the device
Before disabling the pm_runtime, we must ensure that there is no transfer
in progress nor will a new one be started. Otherwise the message pump will
fail and in the end, the process requesting the transfer will be stuck.
This behavior has been observed when transferring data from a SPI flash
with dd while removing the module on a DRA7x-evm.
