qemu: unlink the error report from VIR_STRDUP.

Browse Source 
The function to retrieve the file system info using QEMU-GA is using
some conditionals to retrieve the info. This is wrong because the error
of some conditionals will be raised if VIR_STRDUP return errors and not
if some problem occurred with JSON.
