check the status of every HAL_SPI_ call

[Nati Unger]

Hi,
First thanks for the drivers, I didnt check them yet by hardware, but i want to suggest some things:

1. All the HAL_SPI_ calls has return of success\fail status, it's important to verify them.
2. If there is RTOS, it's better to use mutex.
   What do you think about it?
