mem-cache: Only pendingModified MSHRs can satisfy CMO snoops
We set the satisfied flag when a cache clean request encounters:
1) a block with the dirty bit set, or
2) a pending modified MSHR which means that the cache will get copy of
the block that will be soon modified.
This changeset fixes a previous bug that set the satisfied flag on
snooping MSHR hits even the pendingModified flags was not set.
