[PATCH] mei: vsc: Do not re-enable interrupt from vsc_tp_reset()

[Hans de Goede <hdegoede@redhat.com>]

The only 2 callers of vsc_tp_reset() are:

1. mei_vsc_hw_reset(), which immediataly calls vsc_tp_intr_disable()
   afterwards.

2. vsc_tp_shutdown() which immediately calls free_irq() afterwards.

So neither actually wants the interrupt to be enabled after resetting
the chip and having the interrupt enabled for a short time afer
the reset is undesirable.

Drop the enable_irq() call from vsc_tp_reset(), so that the interrupt
is left disabled after vsc_tp_reset().
