[PATCH] bus/fslmc: fix shadowed variables in queue storage macros

[Weijun Pan <wpan3636@gmail.com>]

The queue storage allocation and free macros declare local variables
named ret and i, which shadow local variables in
rte_dpaa2_create_dpci_device() and trigger -Wshadow warnings.

Rename the macro-local variables to avoid shadowing without changing
behavior.
