objtool: mem*() are not uaccess safe
For mysterious raisins I listed the new __asan_mem*() functions as
being uaccess safe, this is giving objtool fails on KASAN builds
because these functions call out to the actual __mem*() functions
which are not marked uaccess safe.
Removing it doesn't make the robots unhappy.
