[PATCH 1/1] hid: sensor-hub, fix potential memory leak

[Jiri Slaby <jslaby@suse.cz>]

hsdev is not freed in sensor_hub_probe when kasprintf inside the for
loop fails. This is because hsdev is not set to platform_data yet (to
be freed by the code in the err_no_mem label). So free the memory
explicitly in the 'if' branch, as this is the only place where this is
(and will) be needed.
