test(tensilelite): drop stale ffm_fail from 4 StreamK gfx1250 tests (#12065)

## Motivation
- 4 StreamK gfx1250 tests carry the `ffm_fail` marker (expected-fail
under FFM
emulation) but now PASS under emulation. With `xfail_strict = True`, an
XPASS is a hard failure, so the FFM tensilelite leg fails on every PR:
  - `sk_dynamic_sgemm_quick`
  - `sk_dynamic_hgemm_quick`
  - `sk_tdm_general_batched`
  - `sk_hybrid_quick`

## Technical Details
  - Remove stale markers on above StreamK gfx1250 tests
  -  FFM-only, HW unaffected.
 
## Test Plan
- FFM tensilelite gfx1250 leg should clear the 4 XPASS(strict) failures.
- The other `ffm_fail` StreamK tests (`tdm_multicast`) still correctly
XFAIL and are untouched.
  
## Test Result
  - [ ] Verify FFM test passes: TBD

## Submission Checklist

- [x] Look over the contributing guidelines at
https://github.com/ROCm/TheRock/blob/main/GOVERNANCE.md#pull-requests.

## Risk level
Low — test-marker only; no kernel/codegen change. Re-adding the marker
is trivial if a test later regresses on FFM.
