This fixes the two test suite failures that I missed in the PR: https://github.com/llvm/llvm-project/pull/112939 One was a poorly written test case - it assumed that on connect to a gdb-remote with a running process, lldb MUST have fetched all the frame 0 registers. In fact, there's no need for it to do so (as the CallSite patch showed...) and if we don't need to we shouldn't. So I fixed the test to only expect a `g` packet AFTER calling read_registers. The other was a place where some code had used 0 when it meant LLDB_INVALID_LINE_NUMBER, which I had fixed but missed one place where it was still compared to 0.
