mm/mmap.c: remove a never-triggered warning in __vma_adjust()
The upper level of "if" makes sure (end >= next->vm_end), which means
there are only two possibilities:
1) end == next->vm_end
2) end > next->vm_end
remove_next is assigned to be (1 + end > next->vm_end). This means if
remove_next is 1, end must equal to next->vm_end.
The VM_WARN_ON will never trigger.
