Chuck Lever 426b8fb3d6 svcrdma: Hold private mutex while invoking rdma_accept() 
[ Upstream commit 0ac24c320c4d89a9de6ec802591398b8675c7b3c ]

RDMA core mutex locking was restructured by commit d114c6feed
("RDMA/cma: Add missing locking to rdma_accept()") [Aug 2020]. When
lock debugging is enabled, the RPC/RDMA server trips over the new
lockdep assertion in rdma_accept() because it doesn't call
rdma_accept() from its CM event handler.

As a temporary fix, have svc_rdma_accept() take the handler_mutex
explicitly. In the meantime, let's consider how to restructure the
RPC/RDMA transport to invoke rdma_accept() from the proper context.

Calls to svc_rdma_accept() are serialized with calls to
svc_rdma_free() by the generic RPC server layer.
