USB: serial: ftdi_sio: fix latency-timer error handling
[ Upstream commit e3e574ad85a208cb179f33720bb5f12b453de33c ]
Make sure to detect short responses when reading the latency timer to
avoid using stale buffer data.
Note that no heap data would currently leak through sysfs as
ASYNC_LOW_LATENCY is set by default.
