[llvm][NVPTX] Fix RAUW bug in NVPTXProxyRegErasure (#105871)
Fix bug introduced in #105730
The bug is in how the batch RAUW is implemented. If we have
```
%0 = mov %src
%1 = mov %0
use %0
use %1
```
The use of `%1` is rewritten to `%0`, not `%src`. This PR just looks for
a replacement when it maps to the src register, which should
transitively propagate the replacements.
