RDS: Heap OOB write in rds_message_alloc_sgs()
[ Upstream commit c095508770aebf1b9218e77026e48345d719b17c ]
When args->nr_local is 0, nr_pages gets also 0 due some size
calculation via rds_rm_size(), which is later used to allocate
pages for DMA, this bug produces a heap Out-Of-Bound write access
to a specific memory region.
