[PATCH v1 05/24] net/igc/base: reset loop variable

[Anatoly Burakov <anatoly.burakov@intel.com>]

From: Sasha Neftin <sasha.neftin@intel.com>

When writing to Shadow RAM, we set rev_val on success, but since the value
is already set to success initially, it is possible for none of the writes
to be successful, yet ret_val will still be set to success. Fix it by
resetting the ret_val to failure before every loop iteration.

Fixes: 8cb7c57d9b3c ("net/igc: support device initialization")
