[PATCH 3/4] HID: hidraw, fix lock imbalance

[Jiri Slaby]

Add omitted unlock_kernel() to hidraw_ioctl().
Added in 979c407e3b89b606e810fa494ef316896eadbfad
(HID: Push down BKL into ioctl handler in hidraw).

Corresponing sparse warning:
drivers/hid/hidraw.c:267:9: warning: context imbalance in 'hidraw_ioctl': wrong count at exit
drivers/hid/hidraw.c:267:9:    context 'kernel_lock': wanted 0, got 1
