svcrdma: Remove try_module_get from backchannel
Since commit ffe1f0df5862 ("rpcrdma: Merge svcrdma and xprtrdma modules into one"), the forward and backchannel components are part of the same kernel module. A separate try_module_get() call in the backchannel code is no longer necessary. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Reviewed-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
