Gal Pressman 0badf6ffd2 selftests: drv-net: fix RPS mask handling for high CPU numbers 
[ Upstream commit cf055f8c00 ]

The RPS bitmask bounds check uses ~(RPS_MAX_CPUS - 1) which equals ~15 =
0xfff0, only allowing CPUs 0-3.

Change the mask to ~((1UL << RPS_MAX_CPUS) - 1) = ~0xffff to allow CPUs
0-15.

Fixes: 5ebfb4cc30 ("selftests/net: toeplitz test")
