[PATCH net-next 10/11] igc: replace goto out with direct returns in igc_config_fc_after_link_up()

[Tony Nguyen <anthony.l.nguyen@intel.com>]

From: Faizal Rahim <faizal.abdul.rahim@linux.intel.com>

The out: label only returns ret_val with no cleanup. The kernel coding
style guide states: "If there is no cleanup needed then just return
directly." (Documentation/process/coding-style.rst, section 7).

This improves readability ahead of a subsequent patch that introduces a
new goto label in this function.

No functional change.
