Tom 82c4812730 Kernel: Remove flawed SharedInodeVMObject assertion 
This assertion cannot be safely/reliably made in the
~SharedInodeVMObject destructor. The problem is that
Inode::is_shared_vmobject holds a weak reference to the instance
that is being destroyed (ref count 0). Checking the pointer using
WeakPtr::unsafe_ptr will produce nullptr depending on timing in
this case, and WeakPtr::safe_ref will reliably produce a nullptr
as soon as the reference count drops to 0. The only case where
this assertion could succeed is when WeakPtr::unsafe_ptr returned
the pointer because it won the race against revoking it. And
because WeakPtr::safe_ref will always return a nullptr, we cannot
reliably assert this from the ~SharedInodeVMObject destructor.

Fixes #4621
