gpib: agilent_82357a: don't check a NULL serial string
The agilent_82357a driver uses the USB device serial string for device
matching but does not verify that the string exists before passing it
to strcmp().
Verify that the device has a serial number before accessing it to avoid
triggering a NULL-pointer dereference with devices that don't provide
a serial number (iSerialNumber = 0).
Similar to commit aa79f996eb41 ("i2c: cp2615: fix serial string
NULL-deref at probe").
