rt-numa: ignore runtime cpumask if -a CPULIST is specified
When using isolcpus kernel command line option, the CPUs
specified at isolcpus= are not part of the run time environment
cpumask.
This causes "cyclictest -a isolatedcpus" to fail with:
WARN: Couldn't setaffinity in main thread: Invalid argument
FATAL: No allowable cpus to run on
# /dev/cpu_dma_latency set to 0us
To fix this, ignore the runtime cpumask if neither "+", "!"
are specified in the cpu list string.
