xprtrdma: Add trace points for calls to transport switch methods
Name them "trace_xprtrdma_op_*" so they can be easily enabled as a group. No trace point is added where the generic layer already has observability. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
