Bugfix #25657

Three code fixes for 1 report. User experienced crashes while
painting on float buffer + having preview renders on.

- Texture Nodes: Image was re-allocated without using
proper thread lock
- Paint code: old convention to free the byte rect from
a float image as signal to re-create now is a proper
flag. This keeps image memory unchanged. Nice for render.
- Imbuf: call to make a byte rect from float was freeing
mipmaps unnecessary.
