Input: cyttsp5 - fix power control issue on wakeup

commit 7675b5efd81fe6d524e29d5a541f43201e98afa8 upstream.

The power control function ignores the "on" argument when setting the
report ID, and thus is always sending HID_POWER_SLEEP. This causes a
problem when trying to wakeup.

Fix by sending the state variable, which contains the proper HID_POWER_ON or
HID_POWER_SLEEP based on the "on" argument.
