crypto: inside-secure - Base RD fetchcount on actual RD FIFO size
This patch derives the result descriptor fetch count from the actual
FIFO size advertised by the hardware. Fetching result descriptors
one at a time is a performance bottleneck for small blocks, especially
on hardware with multiple pipes. Even moreso if the HW has few rings.
