[PATCH 1/1] fixup! mm: fix a crash due to vma_end_read() that should have been removed

[Suren Baghdasaryan <surenb@google.com>]

Handling a vma lock failure due to vma being detached from under us got
changed but vma_end_read() in that path was left untouched while it should
have been removed. Remove it.

Fixes: 758f7664c3d1 ("mm: replace vm_lock and detached flag with a reference count")
