habanalabs: Call put_pid() when releasing control device
[ Upstream commit 27ac5aada024e0821c86540ad18f37edadd77d5e ]
The refcount of the "hl_fpriv" structure is not used for the control
device, and thus hl_hpriv_put() is not called when releasing this
device.
This results with no call to put_pid(), so add it explicitly in
hl_device_release_ctrl().
