ext4: enable punch hole for bigalloc
After applied this commit (d23142c6), ext4 has supported punch hole for a file system with bigalloc feature. But we forgot to enable it. This commit fixes it. Cc: Lukas Czerner <lczerner@redhat.com> Signed-off-by: Zheng Liu <wenqing.lz@taobao.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
