Remove extraneous land use configuration code in restart

[glemieux]

Task description

This appears to be extraneous code and should be removed:

fates/main/FatesRestartInterfaceMod.F90

Line 2122 in 0f321cd

rio_landuse_config_s => this%rvars(ir_landuse_config_si)%int1d, &

For comparison, this is the relevant restart code that currently exists and is used throughout the module:

fates/main/FatesRestartInterfaceMod.F90

Line 2215 in 0f321cd

rio_landuse_config_si => this%rvars(ir_landuse_config_si)%int1d, &
