mm: fix cache mode tracking in vm_insert_mixed()
commit 87744ab3832b83ba71b931f86f9cfdb000d07da5 upstream
vm_insert_mixed() unlike vm_insert_pfn_prot() and vmf_insert_pfn_pmd(),
fails to check the pgprot_t it uses for the mapping against the one
recorded in the memtype tracking tree. Add the missing call to
track_pfn_insert() to preclude cases where incompatible aliased mappings
are established for a given physical address range.
[groeck: Backport to v4.4.y]
