[PATCH] crypto/scheduler: fix last element for valid args

[Ciara Power]

The list of valid arguments for Scheduler PMD should be terminated with
a NULL entry, as expected by rte_kvargs_parse.
Without this, if an invalid key name was used, a global buffer overflow
occurred resulting in a segmentation fault.

Fixes: 503e9c5afb38 ("crypto/scheduler: register as vdev driver")
