Fix integer sanitizer in clearkey. Calculating index sometimes causes an unsigned integer overflow. This throws a runtime error on integer sanitized builds. runtime error: unsigned integer overflow: 0 - 1 cannot be represented in type 'unsigned int' Since this gets implicitly converted to ssize_t anyhow, make the conversion explicit before decrementing to avoid the overflow. Bug: 30969751 Test: Compiles. Change-Id: Ibd39c1ba0dc64673743672ffc70c22c09f8e828a
