libsmb: Retry with OPEN_REPARSE_POINT on IO_REPARSE_TAG_NOT_HANDLED

Browse Source 
Eventually we'll have to make STOPPED_ON_SYMLINK special to handle the
symlink response, but for now they are the same.

STOPPED_ON_SYMLINK will tell us where the symlink is,
REPARSE_TAG_NOT_HANDLED won't. So if there's an unhandled reparse
point somewhere in the path, there's no really good way to handle
this. We'll get the REPARSE_TAG_NOT_HANDLED the second time as
well. Even SMB1 QPATHINFO gets this when you try to cross a NFS
reparse point.
