[3/3] btrfs: cleanup EXTENT_BUFFER_CORRUPT flag

Commit Message

Daniel Vacek March 25, 2025, 4:31 p.m. UTC

This flag is no longer being used. Remove it.

It was added by commit a826d6dcb32d ("Btrfs: check items for correctness as
we search") but it's no longer being used after commit f26c92386028 ("btrfs:
remove reada infrastructure").
