[PATCH v2 RESEND 16/17] conf: Add return value check to virResctrlAllocForeachCache

[bing.niu@xxxxxxxxx]

From: Bing Niu <bing.niu@xxxxxxxxx>

Add return value check to virResctrlAllocForeachCache in
virDomainCachetuneDefFormat. The virResctrlAllocForeachCache dose have
return value, so need check return value to make sure function executed
without error.
