[PATCH v2] net/intel: Replace manual array size calculation with ARRAY_SIZE

There are still places in the code where manual calculation of array size
exist, but it is good to enforce usage of single macro through the whole
code as it makes code bit more readable.
While at it, beautify condition surrounding it by reversing check and remove
unnecessary casting.
