mm/mmap: Fix error path in do_vmi_align_munmap()
The error unrolling was leaving the VMAs detached in many cases and
leaving the locked_vm statistic altered, and skipping the unrolling
entirely in the case of the vma tree write failing.
Fix the error path by re-attaching the detached VMAs and adding the
necessary goto for the failed vma tree write, and fix the locked_vm
statistic by only updating after the vma tree write succeeds.
Fixes: 763ecb035029 ("mm: remove the vma linked list")
