IB/hfi1: NULL pointer dereference when freeing rhashtable
A NULL pointer dereference occurs when the driver is unloaded, and the SDMA rhashtable is freed if the rhashtable_init() function has not been called. Prevent this by changing sdma_rht to be a pointer to a dynamically allocated hash table. The NULL-ness of the pointer serves as an indication that the hash table was initialized and that it needs to be destroyed.
