net: phy: propagate an error back to the callers of phy_sfp_probe

Browse source 
The compilation warning below reveals that the errors returned from
the sfp_bus_add_upstream() call are not propagated to the callers.
Fix it by returning "ret".

14:37:51 drivers/net/phy/phy_device.c: In function 'phy_sfp_probe':
14:37:51 drivers/net/phy/phy_device.c:1236:6: warning: variable 'ret'
   set but not used [-Wunused-but-set-variable]
14:37:51  1236 |  int ret;
14:37:51       |      ^~~
