[net] ixgbe: phy: fix uninitialized status in ixgbe_setup_phy_link_tnx

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Daniel Borkmann <dborkman@redhat.com>

Status variable is never initialized, can carry an arbitrary value
on the stack and thus may let the function fail.

Fixes: e90dd2645664 ("ixgbe: Make return values more direct")
