igb/igc: use strongly typed pointer
The igb and igc driver both use a trick of creating a local type
pointer on the stack to ease dealing with a receive descriptor in
64 bit chunks for printing. Sparse however was not taken into
account and receive descriptors are always in little endian
order, so just make the unions use __le64 instead of u64.
No functional change.
