[PATCH] fixing crash in irmc.c when vcard=0

[PATCH] fixing crash in irmc.c when vcard=0

[Zheng Wu]

If getting the number of vcard is 0 in sync server, obexd will crash.
The reason is that null point is used in query_result of irmc.c.

The patch itself seems ok to me, but you need to fix your git settings:

1. Don't use Signed-off-by (this is only used for kernel patches).
2. Format your commit message lines to max 72 characters
3. Fix your git author name (first letter capitalized, etc.)

Hi Johan:

For your comments, I will send the patch again after modifying git settings.
