net/mlx4: suppress 'may be used uninitialized' warning
gcc 4.8.4 complains that mlx4_SW2HW_MPT_wrapper() uses an uninitialized
'mpt' variable:
drivers/net/ethernet/mellanox/mlx4/resource_tracker.c: In function 'mlx4_SW2HW_MPT_wrapper':
drivers/net/ethernet/mellanox/mlx4/resource_tracker.c:2802:12: warning: 'mpt' may be used uninitialized in this function [-Wmaybe-uninitialized]
mpt->mtt = mtt;
I think this warning is a false complaint. mpt is only used when
mr_res_start_move_to() return zero, and in all such cases it initializes
mpt. But apparently gcc cannot see that.
Initialize mpt to avoid the warning.
