platform/x86: dell-wmi-sysman: Avoid buffer overflow in current_password_store()

In the Linux kernel, the following vulnerability has been resolved:

platform/x86: dell-wmi-sysman: Avoid buffer overflow in current_password_store()

'length' variable will be zero. Accessing the 'buf' array element with
index 'length - 1' will result in a buffer overflow.

Add a check for an empty string.
