[PATCH v2 1/2] ethdev: fix null pointer dereference

[Ankur Dwivedi <adwivedi@marvell.com>]

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.
As a result of this fix the address sanitizer error observed with
rte_eth_trace_find_next_of() is also resolved.

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