mei: vsc: Don't re-init VSC from mei_vsc_hw_reset() on stop

[ Upstream commit 880af854d6343b796f05b9a8b52b68a88535625b ]

mei_vsc_hw_reset() gets called from mei_start() and mei_stop() in
the latter case we do not need to re-init the VSC by calling vsc_tp_init().

mei_stop() only happens on shutdown and driver unbind. On shutdown we
don't need to load + boot the firmware and if the driver later is
bound to the device again then mei_start() will do another reset.

The intr_enable flag is true when called from mei_start() and false on
mei_stop(). Skip vsc_tp_init() when intr_enable is false.

This avoids unnecessarily uploading the firmware, which takes 11 seconds.
This change reduces the poweroff/reboot time by 11 seconds.
