x86 PAT: remove PFNMAP type on track_pfn_vma_new() error
Impact: fix (harmless) double-free of memtype entries and avoid warning On track_pfn_vma_new() failure, reset the vm_flags so that there will be no second cleanup happening when upper level routines call unmap_vmas(). This patch fixes part of the bug reported here: http://marc.info/?l=linux-kernel&m=123108883716357&w=2 Specifically the error message: X:5010 freeing invalid memtype d0000000-d0101000 Is due to multiple frees on error path, will not happen with the patch below.
