One issue caught by Coverity 340835
*unlock: axgbe_phy_set_mode unlocks pdata->phy_mutex
*double_unlock: axgbe_phy_sfp_detect unlocks pdata->phy_mutex
while it is unlocked.
In axgbe_phy_sfp_detect()/axgbe_phy_set_redrv_mode(),
axgbe_phy_get_comm_ownership() and axgbe_phy_put_comm_ownership()
are invoked subsequently.
Currently in axgbe_phy_get_comm_ownership(), during one of the case
'phy_data->comm_owned' is not protected and before returning 0, lock is
not called and unlock is called in axgbe_phy_put_comm_ownership()
directly which is incorrect.
Ideally, the variable 'phy_data->comm_owned' needs to be protected.
During success scenario, lock is called in
axgbe_phy_get_comm_ownership() followed by unlock in
axgbe_phy_put_comm_ownership(). In failure case, unlock is invoked in
axgbe_phy_get_comm_ownership() itself appropriately.
The fix is to protect 'phy_data->comm_owned' in the identified case
ensuring locks/unlocks properly exist.
