hte: tegra194-test: shut down timer before GPIO release

Browse Source 
tegra_hte_test_remove() releases GPIO descriptors before stopping
hte.timer. gpio_timer_cb() accesses hte.gpio_out and rearms the timer, so
a callback concurrent with remove can use a released descriptor and rearm
after teardown.

Shut down the timer before releasing the GPIO descriptors.
timer_shutdown_sync() waits for a running callback and prevents it from
being rearmed.
