ext4: factor out journalled block zeroing range
Refactor __ext4_block_zero_page_range() by separating the block zeroing
operations for ordered data mode and journal data mode into two distinct
functions:
- ext4_block_do_zero_range(): handles non-journal data mode with
ordered data support
- ext4_block_journalled_zero_range(): handles journal data mode
Also extract a common helper, ext4_load_tail_bh(), to handle buffer head
and folio retrieval, along with the associated error handling. This
prepares for converting the partial block zero range to the iomap
infrastructure.
