Sascha Hauer b33528863d PCI/sysfs: Fix double free in error path 
commit aa382ffa70 upstream.

When pci_create_attr() fails, pci_remove_resource_files() is called which
will iterate over the res_attr[_wc] arrays and frees every non NULL entry.
To avoid a double free here set the array entry only after it's clear we
successfully initialized it.

Fixes: b562ec8f74 ("PCI: Don't leak memory if sysfs_create_bin_file() fails")
