spi: qmsi: Fix enabling the CS line too late
spi: qmsi: Fix enabling the CS line too late

There are situations when the transfer starts before we have the time to
enable the CS line, so to be sure, we active it before even attempting
to start the transfer.

This fixes an CC2520 driver initialization issue using the QMSI SPI driver.
