staging: vt6656: Move device_set_multi code call to vRunCommand

device_set_multi is an atomic call, in order to reduce atomic area of driver
move code to be called from vRunCommand.

Later the atomic area of vRunCommand can be reduced.

Change existing code in device_set_multi to new function
vnt_configure_filter minus its locks.

Change device_set_multi to call bScheduleCommand

device_set_multi is nolonger called from device open.
