RDMA/counter: Only bind user QPs in auto mode

BugLink: https://bugs.launchpad.net/bugs/1892899
[ Upstream commit c9f557421e505f75da4234a6af8eff46bc08614b ]

In auto mode only bind user QPs to a dynamic counter, since this feature
is mainly used for system statistic and diagnostic purpose, while there's
no need to counter kernel QPs so far.
