netdevsim: psp: reset spi on key rotation and check for exhaustion on alloc

The PSP spec states that the lower 31b of the SPI need to be
non-zero. Though not in the spec, I think it is reasonable to reset
the lower 31b of the spi space after a key rotation, and to also
decline to generate session keys when the lower 31b saturate.
