[1/3] btrfs: cleanup EXTENT_BUFFER_READ_ERR flag

Commit Message

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

This flag was added by commit 656f30dba7ab ("Btrfs: be aware of btree inode
write errors to avoid fs corruption") but it stopped being used after commit
046b562b20a5 ("btrfs: use a separate end_io handler for read_extent_buffer").
