Will Deacon f967dfcedb KVM: ARM/arm64: avoid returning negative error code as bool 
commit 18d457661f upstream.

is_valid_cache returns true if the specified cache is valid.
Unfortunately, if the parameter passed it out of range, we return
-ENOENT, which ends up as true leading to potential hilarity.

This patch returns false on the failure path instead.
