Lv Yunlong c178e8a199 net/rds: Fix a use after free in rds_message_map_pages
[ Upstream commit bdc2ab5c61a5c07388f4820ff21e787b4dfd1ced ]

In rds_message_map_pages, the rm is freed by rds_message_put(rm).
But rm is still used by rm->data.op_sg in return value.

My patch assigns ERR_CAST(rm->data.op_sg) to err before the rm is
freed to avoid the uaf.

Fixes: 7dba92037baf3 ("net/rds: Use ERR_PTR for rds_message_alloc_sgs()")
