Pre-allocates fifo pairs in fifo segment.
The number of fifos pre-allocated is the minimum of the requested number of pairs and the maximum number that fit within the segment. If the maximum is hit, the number of fifo pairs requested is updated by subtracting the number of fifos that have been successfully allocated.
