gdb, btrace: fix error diagnostics
When we improved error messages in
cd393cec3ab gdb, btrace: improve error messages
we cleared the original errno. When the error reason can not be explained
in a more detailed error message, and we fall back to the default error
message, it now gives Success as error.
Restore the original errno to fix that.
