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.
