RDMA/erdma: Support create_ah/destroy_ah in non-sleepable contexts
The RDMA CM module might invoke erdma_create_ah() or erdma_destroy_ah()
in a non-sleepable context. Both of these functions will call the
erdma_post_cmd_wait(), which can potentially sleep and occasionally lead
to a hard lockup. Therefore, post the create_ah and destroy_ah commands in
polling mode if the RDMA_CREATE_AH_SLEEPABLE and RDMA_DESTROY_AH_SLEEPABLE
flags are not set, respectively.
