memtrace: Update nBlocks when pointer changes in MemoryShadow::cover

During each ::Map different pointers could be returned by DirectX.
Thus for the same resource with the same subresource having the same size
pointer may change between calls of MemoryShadow::cover. With the pointer
change number of blocks also may change, which may later cause memory
access violation in MemoryShadow::update.

dxgitrace: Fix a thread safety of a d3d11 CreateBuffer method.

According to directx 11 spec all device methods are thread safe:
   "All ID3D11Device interface methods are free-threaded, which means
    it is safe to have multiple threads call the functions
    at the same time."

But all device-context methods according to directx 11 spec:
   "Any context – immediate or deferred – can be used on any thread
    as long as the context is only used in one thread at a time."

So without this fix WrapID3D11Device*::CreateBuffer methods are not
thread safe. It could lead to the crash in some games which are
create buffers in different threads.

memtrace: Fix pointer arithmetic of MemoryShadow::cover

Pointers have unsigned type thus casting them to intptr_t
could lead to a negative value which in one part of the expression
is being implicitly converted to size_t resulting in:
 nBlocks = big_positive_number - negative_number

This rarely happens on x64 but would often happen on x32
resulting in memory access violation.
