mm/mmap: check on file instead of the rb_root_cached of its address_space
In __vma_adjust(), we do the check on *root* to decide whether to adjust
the address_space. It seems to be more meaningful to do the check on
*file* itself. This means we are adjusting some data because it is a file
backed vma.
Since we seem to assume the address_space is valid if it is a file backed
vma, let's just replace *root* with *file* here.
