net/sfc/base: move Rx descs number check to generic place

Now we have min/max limits in NIC config, so we can do check against
min/max in a generic place instead of NIC family specific functions.
Check that the descriptors number is a power of 2 is also can be
made common. It removes code duplication and makes NIC family
specific functions a bit shorter.
