[ Upstream commit 8a54d8fc160e67ad485d95a0322ce1221f80770a ]
Pointer arithmetic already adjusts by the size of the struct,
so the sizeof() calculation is wrong. This is basically the
same as Colin King's patch for similar code in the iwlwifi
driver.
Fixes: 230ebaa189af ("cfg80211: read wmm rules from regulatory database")
