Bluetooth: Controller: mayfly enable to supercede over disable

If mayfly enable is called before mayfly could be disabled,
then enable shall supercede disabling, the mayfly will
remain enabled. Any new mayfly enqueued by the caller that
tried to disable mayfly will be chain for deferred
executon under this condition.

The BLE Controller's connection update procedure broke when
mayfly implementation was updated to defer disabling until
all queued mayfly where completed. Mayfly is disabled
between ticker_stop and ticker_start calls to chain them
so that ticker does not power off counter h/w if the ticker
being stopped is last one.

This commit fixes the connection update procedure which
used the mayfly enable before mayfly disable could
complete.
