Suren Baghdasaryan cc483b3288 mm: limit the scope of vma_start_read() ...

Limit the scope of vma_start_read() as it is used only as a helper for
higher-level locking functions implemented inside mmap_lock.c and we are
about to introduce more complex RCU rules for this function.  The change
is pure code refactoring and has no functional changes.
