Sowmini Varadhan d4014d8cc6 rds: do not call ->conn_alloc with GFP_KERNEL 
Commit ebeeb1ad9b ("rds: tcp: use rds_destroy_pending() to synchronize
netns/module teardown and rds connection/workq management")
adds an rcu read critical section to __rd_conn_create. The
memory allocations in that critcal section need to use
GFP_ATOMIC to avoid sleeping.

This patch was verified with syzkaller reproducer.
