x86/mpx: Use compatible types in comparison to fix sparse error
[ Upstream commit 453828625731d0ba7218242ef6ec88f59408f368 ]
info->si_addr is of type void __user *, so it should be compared against
something from the same address space.
This fixes the following sparse error:
arch/x86/mm/mpx.c:296:27: error: incompatible types in comparison expression (different address spaces)
