[RFC PATCH 14/19] net/e1000: fix build with shadow warnings enabled

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

Variable "ret" was shadowed within the close function, so rename outer
variable to "retval" to clear the warnings.

Fixes: 62024eb82756 ("ethdev: change stop operation callback to return int")
Cc: stable@dpdk.org
