Some SPI devices have a timeout in the secuence.
You can do:

a) Get a derivate with a SPI interface in hard
b) as mr. Karas says put the SPI code in the interrupt routine
c) Use a flag:
When you execute the interrupt code set a flag, the SPI code must clear the flag at the start and if the flag is active at the end then re-execute the SPI code because the data should be corrupted.
