[PATCH] btrfs-progs:qgroup:make large size aligned

[Fan Chengniang]

problem: when the size is too big, the output format will be unaligned.
the __update__columns_max_len function has been updated to fix this
problem

In my patch "[PATCH v3] make btrfs qgroups show human readable sizes"
I forget to update the function __update__columns_max_len which may
cause large size unaligned.
