fix: guard arg.Print() in WMMA bwd data grouped conv with log
 level check (#9232)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

## Motivation

Resolves https://github.com/ROCm/ROCm/issues/6403.

## Technical Details

Stray `arg.Print()` was causing a flood of debug lines when running a
torch reproducer that triggers backward-data WMMA grouped-conv path on
gfx1151. For example,
```
a_grid_desc_m_ak_container{7744, 7520}
b_grid_desc_n_bk_container_{64, 7520}
e_grid_desc_mblock_mperblock_nblock_nperblock_container_{7744, 64}
a_grid_desc_m_ak_container_{7808, 5024}
b_grid_desc_n_bk_container_{128, 5024}
e_grid_desc_mblock_mperblock_nblock_nperblock_container_{7808, 128}
```
Guarded the `arg.Print()` with a log level check
`stream_config.log_level_ > 0`, matching the logic found in other
``arg.Print()`` statements,

## Test Plan

Compile example
(`example/38_grouped_conv_bwd_data_multiple_d/grouped_conv_bwd_data_wmma_v3_fp16.cpp`)
and run binary against both patched and unpatched header. Check output
to see that debug logging is no longer present with patched version.

## Test Result
Unpatched output (flood present):
  ```
out: dim 5, lengths {32, 4, 192, 28, 28}, strides {602112, 150528, 1,
5376, 192}
wei: dim 5, lengths {32, 192, 192, 3, 3}, strides {331776, 1728, 1, 576,
192}
in: dim 5, lengths {32, 4, 192, 28, 28}, strides {602112, 150528, 1,
5376, 192}
  a_grid_desc_m_ak_container_{3136, 1728}
  b_grid_desc_n_bk_container_{192, 1728}
  e_grid_desc_mblock_mperblock_nblock_nperblock_container_{3136, 192}
  Perf: 0 ms, inf TFlops, inf GB/s
```
  Patched output (flood gone, conv still runs):
  ```
  out: dim 5, lengths {32, 4, 192, 28, 28}, strides {602112, 150528, 1, 5376, 192}
  wei: dim 5, lengths {32, 192, 192, 3, 3}, strides {331776, 1728, 1, 576, 192}
  in:  dim 5, lengths {32, 4, 192, 28, 28}, strides {602112, 150528, 1, 5376, 192}
  Perf: 0 ms, inf TFlops, inf GB/s
```
