[PATCH 4/4] mm/vmalloc: Rename the variable real_align to original_align to prevent misunderstanding

[Liu Ye <liuye@kylinos.cn>]

The real prefix is generally used to indicate the adjusted value of a
parameter, but according to the code logic, it should indicate the
original value, so it is recommended to rename it to original_align.
