Log:
MoH: Undo commit r416150 (1.8)

This patch reverts r416150. When the comparison between mohclass->name and
state->class->name is made, you are not guaranteed that (a) state->class is
non-NULL or that state or state->class are in a safe state.

Crashes caught by the bridges/transfer_capabilities test.
