[PATCH 1/2] eventdev: fix vector adapter power-of-2 size check

[pbhagavatula at marvell.com]

From: Pavan Nikhilesh <pbhagavatula at marvell.com>

validate_conf() rejected valid configurations and accepted invalid
ones: when the adapter requires a log2 vector size it errored out if
the size *was* a power of 2 (rte_is_power_of_2() != 0) instead of when
it was not. Invert the condition to reject non-power-of-2 sizes.

Fixes: e12c3754da7a ("eventdev/vector: introduce event vector adapter")
