[dpdk-dev] [PATCH 2/2] net/thunderx: fix unused function nicvf_mbox_msg_str error

[Jerin Jacob <jerin.jacob@caviumnetworks.com>]

Fix the following error with clang
	error: unused function 'nicvf_mbox_msg_str'

The nicvf_mbox_msg_str() maybe unused, based on DEBUG
compilation option selected. Mark __attribute__((unused)) on
this function, to inform compiler that this function may be unused

Fixes: e93592f1 ("net/thunderx/base: add mbox APIs for PF/VF communication")
