msi(1/3): Don't crash if rec is NULL

Your patches also cure the symptom, Juan; thanks.
I agree with the concerns James expressed, though: I didn't feel that I
understood the whole story. (Heck, I really have *no* clue what I'm
talking about <grin>).
However, the call to MSI_FormatMessageW is not an internal call, I think;
it looks to me as though it's called as a direct result of an inbound
call to MsiFormatRecordA():
0014:Call msi.MsiFormatRecordA(00000002,00000005,1000e768,7b7ea55c) ret=10003064
(in http://bugs.winehq.org/attachment.cgi?id=8060 about 10-15 lines from bottom)
So the question in my mind is:
Can a record still be a legitimate record if MSI_RecordGetFieldCount returns 0?
If the answer is yes, then I think the patches are correct.
Cheers,
Jeremy
