nfc: change order inside nfc_se_io error path
commit7d834b4d1a
upstream. cb_context should be freed on the error path in nfc_se_io as stated by commit25ff6f8a5a
("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.
