net/ice: increase max Rx/Tx descriptors

Intel PMDs are capped by default to only 4096 Rx/Tx descriptors. This can be limiting for applications requiring a bigger buffer capabilities. By bufferring more packets with Rx/Tx descriptors, the applications can better handle the processing peaks. Setting ice max descriptors to 8192 - 32 as per datasheet maximum.
