@Jampag tested this patch and reported on Arduino Forum that it does indeed fix #493:

I just checked with an oscilloscope that the frequency remains the set one and no longer 1MHz.

This PR solves #493.
The SPI settings were not updated in the strange context of the issue because the begin() function did update SPI setting without storing the values into the stored SPI settings (stored SPI settings are used to avoid the update of the settings in case new setting are the same of the ones already used).
