i40evf_execute_vf_cmd() uses _atomic_set_cmd() to execute virtual
channel commands safely in multi-process mode and multi-thread mode.
However, it returns -1 when one process or thread is pending. Add
rte_spinlock_trylock() to handle this issue in concurrent scenarios.
Should '_atomic_set_cmd()' removed, since spinlock it added?
