Vernon Yang 80a4bcac69 mm: khugepaged: set to next mm direct when mm has MMF_DISABLE_THP_COMPLETELY
When an mm with the MMF_DISABLE_THP_COMPLETELY flag is detected during
scanning, directly set khugepaged_scan.mm_slot to the next mm_slot, reduce
redundant operation.

Without this patch, entering khugepaged_scan_mm_slot() next time, we will
set khugepaged_scan.mm_slot to the next mm_slot.

With this patch, we will directly set khugepaged_scan.mm_slot to the next
mm_slot.
