svcrdma: Remove try_module_get from backchannel

Browse Source 
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.
