HID: fix incorrect free in hiddev
If hiddev_open() fails, it wrongly frees the shared hiddev structure
kept in hiddev_table instead of the hiddev_list structure allocated
for the opened file descriptor. Existing references to this structure
will then accessed free memory.
This was introduced by 079034073 "HID: hiddev cleanup -- handle all
error conditions properly".
