rpcrdma: Merge svcrdma and xprtrdma modules into one
Bi-directional RPC support means code in svcrdma.ko invokes a bit of code in xprtrdma.ko, and vice versa. To avoid loader/linker loops, merge the server and client side modules together into a single module. When backchannel capabilities are added, the combined module will register all needed transport capabilities so that Upper Layer consumers automatically have everything needed to create a bi-directional transport connection. Module aliases are added for backwards compatibility with user space, which still may expect svcrdma.ko or xprtrdma.ko to be present. This commit reverts commit 2e8c12e1b765 ("xprtrdma: add separate Kconfig options for NFSoRDMA client and server support") and provides a single CONFIG option for enabling the new module.
