lib/event: remove deprecated ReactorMask from legacy config

Browse Source 
Legacy INI configuration is being removed this release.
This patch removes one of its options and always uses the
SPDK_APP_DPDK_DEFAULT_CORE_MASK as default core mask.

That can only be overwriten by -m/--cpumask arguments in app.

In bdevperf there was no reason to set reactor_mask to NULL,
as that was then still using the defaults.

Meanwhile bdev_svc will now check if user provided different
string via command line args to know if it should
unaffinitize its thread.
