Sowmini Varadhan 53d0e83f93 rds: tcp: must use spin_lock_irq* and not spin_lock_bh with rds_tcp_conn_lock 
rds_tcp_connection allocation/free management has the potential to be
called from __rds_conn_create after IRQs have been disabled, so
spin_[un]lock_bh cannot be used with rds_tcp_conn_lock.

Bottom-halves that need to synchronize for critical sections protected
by rds_tcp_conn_lock should instead use rds_destroy_pending() correctly.

Fixes: ebeeb1ad9b ("rds: tcp: use rds_destroy_pending() to synchronize
       netns/module teardown and rds connection/workq management")
