qlcnic: fix memory leak in qlcnic_sriov_channel_cfg_cmd()

[ 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.
