binder_alloc: Add missing mmap_lock calls when using the VMA
Take the mmap_read_lock() when using the VMA in
binder_alloc_print_pages() and when checking for a VMA in
binder_alloc_new_buf_locked().
It is worth noting binder_alloc_new_buf_locked() drops the VMA read lock
after it verifies a VMA exists, but may be taken again deeper in the
call stack, if necessary.
Fixes: a43cfc87caaf (android: binder: stop saving a pointer to the VMA)
