windows: Fix another CreateFile usage.

Browse Source 
When built with MSVC with unicode enabled, this gave:

warning C4133: 'function': incompatible types - from 'char *' to 'LPCWSTR'

due to CreateFile expanding to CreateFileW which accepts UTF-16 filenames.

The device name used here is in 8-bit format, having come from a call to
wc_to_utf8() in either get_root_hub_name() or get_external_hub_name(). So
we need to use CreateFileA.
