spi/m68knommu: Coldfire QSPI platform support
After grabbing a msg from the msgq, the mcfqspi_work function calls list_del_init on the mcfqspi->msgq which unintentionally deletes the rest of the list before it can be processed. If qspi call was made using spi_sync, this can result in a process hang.
