[BugFix]fix deepseek torchair recompile (#3678)

### What this PR does / why we need it?
The #3624 PR fix the precision of deepseek torchair, but don't consider
the limitation of torch compile which results in the recompile, This PR
fixs this problem

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
