ena-com: Fix ena-com to allocate cdesc aligned to 4kvendor/ena-com/2.2.1
The latest generation hardware requires IO CQ (completion queue) descriptors memory to be aligned to a 4K. It needs that feature for the best performance. Allocating unaligned descriptors will have a big performance impact as the packet processing in a HW won't be optimized properly. It's a critical fix, especially for the arm64 EC2 instances.
