[ Upstream commit 9d8a99c5a7c7f4f7eca2c168a4ec254409670035 ]
In one of the error paths in qlcnic_sriov_channel_cfg_cmd(), the memory allocated in qlcnic_sriov_alloc_bc_mbx_args() for mailbox arguments is not freed. Fix that by jumping to the error path that frees them, by calling qlcnic_free_mbx_args(). This was found using static analysis.
