Motivation

Minor bug fix in the argument of a function in kernelwriter.py

Technical Details

getWaitcntCodeForDirectToVgpr() requires five parameters. Two parameters are missing at the function call site.
This PR adds these parameters.

Test Plan

Use CI

* [CK_TILE] FMHA BWD Optimization For GFX950 (#2628)

* simplify fmha_bwd_kernel MakeKargs & dq_dram_window

* simply duplicate

* trload pipeline

* Try two-stage

* add prefetch

* optimize & iglp

* Fix num_byte calculations to use nhead_k for K & V size (#2653)

Simple fix just to calculate the number of bytes correctly for what's reported in the output. I was getting 6200 GB/s which is past the SoL of MI300.

Before:
```
./bin/tile_example_fmha_fwd -prec=bf16 -b=2 -s=1 -s_k=32768 -h=32 -h_k=8 -d=128 -page_block_size=128 -num_splits=8 -iperm=0 -operm=0 -v=0 -kname=1
[bf16|batch|bshd] b:2, h:32/8, s:1/32768, d:128/128, scale_s:0.0883883, bias:n, p_drop:0, lse:0, squant:0, mask:n, v:r, num_splits:8, page_block_size:128, fmha_fwd_splitkv_d128_bf16_batch_b16x64x64x128x64x128_r1x4x1_r1x4x1_w16x16x16_w16x16x16_qr_nwarp_sshuffle_vr_ps_nlogits_nbias_nmask_lse_nsquant_pagedkv, fmha_fwd_splitkv_combine_d128_bf16_batch_b32_unused_ps_nlse_nsquant, 0.173 ms, 6.20 TFlops, 6202.95 GB/s
```

After:
```
./bin/tile_example_fmha_fwd -prec=bf16 -b=2 -s=1 -s_k=32768 -h=32 -h_k=8 -d=128 -page_block_size=128 -num_splits=8 -iperm=0 -operm=0 -v=0 -kname=1
