ACPI: TAD: Rearrange runtime PM operations in acpi_tad_remove()
It is not necessary to resume the device upfront in acpi_tad_remove()
because both acpi_tad_disable_timer() and acpi_tad_clear_status()
attempt to resume it, but it is better to prevent it from suspending
between these calls by incrementing its runtime PM usage counter.
Accordingly, replace the pm_runtime_get_sync() call in acpi_tad_remove()
with a pm_runtime_get_noresume() one and put the latter right before the
first invocation of acpi_tad_disable_timer().
In addition, use pm_runtime_put_noidle() to drop the device's runtime
PM usage counter after using pm_runtime_get_noresume() to bump it up
to follow a common pattern and use pm_runtime_suspend() for suspending
the device afterward.
No intentional functional impact.
