hw/ssi/xilinx_spips: Fix flash erase assert in dual parallel configuration

Ensure that the FIFO is checked for emptiness before popping data
from it.  Previously, the code directly popped the data from the FIFO
without checking, which could cause an assertion failure:

../util/fifo8.c:67: fifo8_pop: Assertion `fifo->num > 0' failed.
