Fixed, thanks!

The new commit message is the following:

| FFI: Add tonumber() specialization for failed conversions.
|
| Contributed by Javier Guerra Giraldez.
|
| (cherry picked from commit 02b521981a1ab919ff2cd4d9bcaee80baf77dce2)
|
| When `tonumber()` is recorded (as a part of a trace) for a cdata
| argument that can't be converted to a number, the `nil` value is recorded
| as the yielded result. But without special check on trace for cdata type
| this `nil` will be returned for another type of cdata that can be
| converted.
|
| This patch adds the corresponding check for recording of failed cdata
| conversions.
