Subject: [PATCH net v2] selftests: net: fix rps_default_mask with >32 CPUs

If there is more than 32 cpus the bitmask will start to contain
commas, leading to:

./rps_default_mask.sh: line 36: [: 00000000,00000000: integer expression expected

Remove the commas, bash doesn't interpret leading zeroes as oct
so that should be good enough.

Fixes: c12e0d5f267d ("self-tests: introduce self-tests for RPS default mask")
Signed-off-by: Jakub Kicinski <kuba@...nel.org>

v2:
 - remove all commas
v1: https://lore.kernel.org/all/20240119151248.3476897-1-kuba@kernel.org/
