[PATCH v1 1/2] ethdev: fix null pointer dereference

[Ankur Dwivedi]

The speed_fec_capa pointer can be null. So dereferencing the pointer is
removed and only the pointer is captured in trace function.
Fixed few more trace functions in which null pointer can be dereferenced.

Coverity issue: 383238
Bugzilla ID: 1162
Fixes: 6679cf21d608 ("ethdev: add trace points")
Fixes: ed04fd4072e9 ("ethdev: add trace points for flow")
