net/ixgbe/base: acquire PHY semaphore before device reset

A recent firmware change fixed an issue to acquire the PHY semaphore
before accessing PHY registers. This led to a case where SW can issue
a device reset clearing the MDIO registers. This patch makes SW acquire
the PHY semaphore before issuing a device reset.
