During cnss unload or error quit, cnss_dms_deinit() is called to
perform dms client deinit. When dms sever quit, modem also send event
to cnss to schedule dms client restart with dms_del_server(). The two
processes are asynchronous so qmi_handle_release() may be entered
twice and cause qmi->sock to be used after free.
To avoid this race condition, call cnss_cancel_dms_work() before
cnss_dms_deinit() to guarantee the two processes not run concurrently.

For dual chip solution, first chip may fail to probe because of pcie
driver is not ready. During second chip probing, first chip may retry
to probe. So, second chip may set/get plat_env[0], first chip may
set/get plat_env[1].
If sencond chip not attached, plat_env[0] will be cleaned. When
cnss_pci_probe() is called by first chip, cnss_get_plat_priv_by_rc_num()
will call plat_env[0]. However it is already NULL.
