ext4: remove ext4_handle_release_buffer()
ext4_handle_release_buffer() was intended to remove journal write access from a buffer, but it doesn't actually do anything at all other than add a BUFFER_TRACE point, but it's not reliably used for that either. Remove all the associated dead code. Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Reviewed-by: Carlos Maiolino <cmaiolino@redhat.com>
