vma_is_special_huge() tests whether either the VMA_PFNMAP_BIT or
VMA_MIXEDMAP_BIT is set (i.e. whether the VMA is not mm-managed),

DAX however no longer sets VMA_MIXEDMAP_BIT, so this carve-out is no longer
required.
Therefore test for !vma_is_mm_managed() instead and also drop the
VMA_IO_BIT check, as it is now redundant since it is enforced that
mm-managed mappings may not set VMA_IO_BIT.
This also eliminates another overloaded use of 'special' within mm.
No functional change intended.
