ksmbd: wait for deferred notify cancellation

Browse source

A cancelled SMB2 CHANGE_NOTIFY request is completed from system_wq. The
deferred work keeps a reference to the connection, but it is not included
in the connection's r_count. During connection teardown,
ksmbd_conn_transport_destroy() can therefore finish the connection handler
and destroy session proc entries before the deferred response runs.

Account for the deferred cancellation work in r_count. The connection
handler now waits for the deferred response to finish before it
deregisters sessions and removes their proc entries.
