Yuanyuan Zhong 6d065f507d mm: /proc/pid/smaps_rollup: avoid skipping vma after getting mmap_lock again ...

After switching smaps_rollup to use VMA iterator, searching for next entry
is part of the condition expression of the do-while loop.  So the current
VMA needs to be addressed before the continue statement.

Otherwise, with some VMAs skipped, userspace observed memory
consumption from /proc/pid/smaps_rollup will be smaller than the sum of
the corresponding fields from /proc/pid/smaps.
