net: thunderx: remove set but not used variable 'tail'
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/net/ethernet/cavium/thunder/nicvf_queues.c: In function nicvf_sq_free_used_descs:
drivers/net/ethernet/cavium/thunder/nicvf_queues.c:1182:12: warning:
variable tail set but not used [-Wunused-but-set-variable]
It's not used since commit 4863dea3fab01("net: Adding support for Cavium ThunderX network controller"),
so remove it.
