i40e: fix warning about shadowed ring parameter
In commit 147e81ec7568 ("i40e: Test memory before ethtool alloc succeeds")
code was added to handle ring allocation on systems with low memory.
It shadowed the ring parameter pointer by introducing a local ring
pointer inside the for loop. Most of the code in the loop already just
accessed the ring via &rx_rings[i]. Since most of the code already does
this, just remove the local variable.
If someone considers it worth keeping a local around, they should use it
for the whole section instead of just a couple of accesses.
This fixes a warning when -Wshadow is enabled
