That timer was introduced with commit 6bd32326cda(Bluetooth: Use
proper timer for hci command timout)
Timer seems to be running when the thing is closed. Removing the timer
unconditionally fixes the problem. And yes, it needs to be fixed
before the HCI_UP check.

The current implementation of hidp_output_raw_report() relies only on
the Control channel even for Output reports, and the BT HID
specification [1] does not mention using the DATA message for Output
reports on the Control channel (see section 7.9.1 and also Figure 11:
SET_ Flow Chart), so let us just use SET_REPORT.
This also fixes sending Output reports to some devices (like Sony
Sixaxis) which are not able to handle DATA messages on the Control
channel.
Ideally hidp_output_raw_report() could be improved to use this scheme:
Feature Report -- SET_REPORT on the Control channel
Output Report -- DATA on the Interrupt channel
for more efficiency, but as said above, right now only the Control
channel is used.
