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.

Fixes: f197a7aa6288 ("qlcnic: VF-PF communication channel implementation")
