Xen devel - Feb 2009 - [PATCH] XendAPIStore - do not remove non-existent item

If list is searched and item not found, then don''t attempt to delete
the
item.

I''ve seen this bug manifest as

xen81:~/bin # xm li
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0  3151    16     r-----   1240.8
pxe                                          3   256     1     -b----     26.4
xen81:~/bin # xm des 3
Error: (''d59cd309-80cd-66b3-d4f3-cff439eadc8a'',
''VM_metrics'')
Usage: xm destroy <Domain>

Terminate a domain immediately.


I''m not sure why this vm had no metrics object associated with it but
nonetheless I don''t think we should be throwing exceptions by removing
non-existent objects from XendAPIStore.
