High: crmd: Prevent use-after-free in lrm interface code (Patch based on work by Keisuke MORI)

• An element of pending_ops is removed at lrm.c:497
• It is called inside from g_hash_table_foreach() at lrm.c:1475
• This is violating the usage of g_hash_table_foreach() according to the glib manual.
• Therefore the iteration can not proceed correctly and would try to refer to a removed element.
