fixed a bug that broke lc_names assignment during MOF RACs calculation

[husainadamji]

Previously, lc_names was assigned descriptor_names if j = 0. This assumed that the first linker in the linker list will always be connected to the SBU. This may not be the case all the time. Fixed this by tracking first instance of SBU-connected linker with a boolean.
