[RFC PATCH 18/19] net/ixgbe: fix build with shadow warnings enabled

[Bruce Richardson <bruce.richardson@intel.com>]

The loop counter "i" was shadowed, with it being used in a macro and
also as a local variable in the function using that macro. Fix the issue
by making "i" a loop-local variable in all contexts.

Fixes: 76c6f89e80d4 ("ixgbe: support new flow director masks")
Fixes: 2c6b19af78e3 ("ethdev: increase flow type limit from 32 to 64")
Cc: stable@dpdk.org
