net: dsa: bcm_sf2: fix buffer overflow doing set_rxnfc
[ Upstream commit f949a12fd697479f68d99dc65e9bbab68ee49043 ]
The "fs->location" is a u32 that comes from the user in ethtool_set_rxnfc().
We can't pass unclamped values to test_bit() or it results in an out of
bounds access beyond the end of the bitmap.
