RDMA/usnic: Fix memleak in find_free_vf_and_create_qp_grp
commit a306aba9c8d869b1fdfc8ad9237f1ed718ea55e6 upstream.
If usnic_ib_qp_grp_create() fails at the first call, dev_list
will not be freed on error, which leads to memleak.
Fixes: e3cf00d0a87f ("IB/usnic: Add Cisco VIC low-level hardware driver")
