x86: Don't check for BIOS corruption in first 64K when there's no need to Due to commit 781c5a67f152c17c3e4a9ed9647f8c0be6ea5ae9 it is likely that the number of areas to scan for BIOS corruption is 0 -- especially when the first 64K is already reserved (X86_RESERVE_LOW is 64K by default). If that's the case then don't set up the scan.
