[dpdk-dev] [PATCH] net/qede: only access sw rx ring index for debug

[David Marchand <david.marchand@redhat.com>]

Caught by clang, this idx value is only used for a debug message when
the mbufs allocation fails.
No need to use idx as a temporary storage.

Fixes: 8f2312474529 ("net/qede: fix performance bottleneck in Rx path")
