[PATCH v1 2/6] xprtrdma: Clean up synopsis of rpcrdma_req_create()

[Chuck Lever <chuck.lever@xxxxxxxxxx>]

Commit 1769e6a816df ("xprtrdma: Clean up rpcrdma_create_req()")
added rpcrdma_req_create() with a GFP flags argument in case a
caller might want to avoid waiting for memory.

There has never been a caller that does not pass GFP_KERNEL as
the third argument. That argument can therefore be eliminated.
