netdrvr: atl1e: Don't take the mdio_lock in atl1e_probe
commit f382a0a8e9403c6d7f8b2cfa21e41fefb5d0c9bd upstream Lockdep warns about the mdio_lock taken with interrupts enabled then later taken from interrupt context. Initially, I considered changing these to spin_lock_irq/spin_unlock_irq, but then I looked at atl1e_phy_init() and saw that it calls msleep(). Sleeping while holding a spinlock is not allowed either. In the probe path, we haven't registered the interrupt handler, so it can't poke at this card yet. It's before we call register_netdev(), so I don't think any other threads can reach this card either. If I'm right, we don't need a spinlock at all.
