RDMA/hfi1: Prevent memory leak in sdma_init

Browse Source 
[ Upstream commit 34b3be18a04ecdc610aae4c48e5d1b799d8689f6 ]

In sdma_init if rhashtable_init fails the allocated memory for
tmp_sdma_rht should be released.

Fixes: 5a52a7acf7e2 ("IB/hfi1: NULL pointer dereference when freeing rhashtable")
