RDMA/cm: Replace pr_debug() call sites with tracepoints
In the interest of converging on a common instrumentation infrastructure,
modernize the pr_debug() call sites added by commit 119bf81793ea ("IB/cm:
Add debug prints to ib_cm"). The new tracepoints appear in a new "ib_cma"
subsystem.
The conversion is somewhat mechanical. Someone more familiar with the
semantics of the recorded information might suggest additional data
capture.
Some benefits include:
- Tracepoints enable "always on" reporting of these errors
- The error records are structured and compact
- Tracepoints provide hooks for eBPF scripts
Sample output:
nfsd-1954 [003] 62.017901: icm_dreq_skipped: local_id=1998890974 remote_id=1129750393 state=DREQ_RCVD lap_state=LAP_UNINIT
