Venki Pallipadi dee7cbb210 x86: PAT bug fix for attribute type check after reserve_memtype
Bug fixes for reserve_memtype() call in __ioremap and pci_mmap_page_range().
If reserve_memtype returns non-zero, then it is an error and subsequent free is
not required. Requested and returned prot value check should be done when
reserve_memtype returns success.
