Subject: [PATCH net v2] igc: igc_read_phy_reg_gpy: drop premature return

igc_read_phy_reg_gpy checks the return value from igc_read_phy_reg_mdic
and if it's not 0, returns immediately. By doing this, it leaves the HW
semaphore in the acquired state.

Drop this premature return statement, the function returns after
releasing the semaphore immediately anyway.
