nfc: change order inside nfc_se_io error path

Browse Source 
commit 7d834b4d1ab66c48e8c0810fdeadaabb80fa2c81 upstream.

cb_context should be freed on the error path in nfc_se_io as stated by
commit 25ff6f8a5a3b ("nfc: fix memory leak of se_io context in
nfc_genl_se_io").

Make the error path in nfc_se_io unwind everything in reverse order, i.e.
free the cb_context after unlocking the device.
