HID: Consolidate device existence checks in hiddev_ioctl
Currently, if the device has been removed before hiddev_ioctl(), the -EIO is returned. If it's removed while hiddev_ioctl() is in progress, some commands are still processed fine, others return -ENODEV. This change takes the "existancelock" before processing ioctl commands and releases it at the end. If the device has been removed, always returns -ENODEV.
