PCI/sysfs: Use correct variable for the legacy_mem sysfs object
[ Upstream commit 045a927 ] Two legacy PCI sysfs objects "legacy_io" and "legacy_mem" were updated to use an unified address space in the commit 636b21b ("PCI: Revoke mappings like devmem"). This allows for revocations to be managed from a single place when drivers want to take over and mmap() a /dev/mem range. Following the update, both of the sysfs objects should leverage the iomem_get_mapping() function to get an appropriate address range, but only the "legacy_io" has been correctly updated - the second attribute seems to be using a wrong variable to pass the iomem_get_mapping() function to. Thus, correct the variable name used so that the "legacy_mem" sysfs object would also correctly call the iomem_get_mapping() function.
