ext4: fix compile error when using BUFFER_TRACE

commit ddccb6dbe780d68133191477571cb7c69e17bb8c upstream.

Fix compile error below when using BUFFER_TRACE.

fs/ext4/inode.c: In function ‘ext4_expand_extra_isize’:
fs/ext4/inode.c:5979:19: error: request for member ‘bh’ in something not a structure or union
  BUFFER_TRACE(iloc.bh, "get_write_access");

Fixes: c03b45b853f58 ("ext4, project: expand inode extra size if possible")
