power: sequencing: fix NULL-pointer dereference in pwrseq_unit_new()

Browse Source 
If memory allocation fails in pwrseq_unit_setup_deps(), pwrseq_unit_put()
is called to release the partially initialized unit. However, we've
never initialized unit->list and pwrseq_unit_release() will
unconditionally call list_del() on it. Initialize unit->list right after
allocating the unit struct.
