[blktests,2/4] tests, common: Get rid of _have_null_blk

Commit Message

Li Zhijian Jan. 7, 2025, 6:19 a.m. UTC

- _have_null_blk is same with _have_driver null_blk, it seems there is no
a strong opinion to keep it.
- In addition, '_have_module_param null_blk' will test _have_driver first,
  that means it's safe to remove its former _have_driver in require()
