selftests: drv-net: fix RPS mask handling in toeplitz test 



The toeplitz.py test passed the hex mask without "0x" prefix (e.g.,
"300" for CPUs 8,9). The toeplitz.c strtoul() call wrongly parsed this
as decimal 300 (0x12c) instead of hex 0x300.

Pass the prefixed mask to toeplitz.c, and the unprefixed one to sysfs.
