RDMA/nes: Make nesadapter->phy_lock usage consistent
nes_{read,write}_1G_phy_reg() are using phy_lock while nes_{read,write}_10G_phy_reg() leave that to the caller. Remove phy_lock from 1G routines and leave the locking to the caller. Add additional phy_lock calls around 1G read/write. Signed-off-by: Chien Tung <chien.tin.tung@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
