logic reversal in StackFrame::Disassemble in r287189

I think something went wrong in r287189:

https://github.com/llvm-mirror/lldb/commit/dfd7c7c89c00bbffcb130cf51cd33058ecb5dfcd#diff-3adb8d2b6f1642f0ae63c3cd9326d6e4L221

First it checked if the disassembly was empty, if not it filled it, now it returns null if it's empty (which it will always be initially)

Thanks for the heads up, it does indeed look like an issue. Wonder why it was only just now caught. I’ll submit a fix shortly.
