net: marvell: mvpp2: Fix the computation of shared CPUs
commit b83f5ac7d922e69a109261f5f940eebbd4e514c4 upstream.
'bitmap_fill()' fills a bitmap one 'long' at a time.
It is likely that an exact number of bits is expected.
Use 'bitmap_set()' instead in order not to set unexpected bits.
Fixes: e531f76757eb ("net: mvpp2: handle cases where more CPUs are available than s/w threads")
