PCI: endpoint: pci-epf-vntb: Fix the incorrect usage of __iomem attribute
__iomem attribute is supposed to be used only with variables holding the
MMIO pointer. But here, 'mw_addr' variable is just holding a 'void *'
returned by pci_epf_alloc_space(). So annotating it with __iomem is clearly
wrong. Hence, drop the attribute.
This also fixes the below sparse warning:
drivers/pci/endpoint/functions/pci-epf-vntb.c:524:17: warning: incorrect type in assignment (different address spaces)
