cifs: add a helper to find an existing readable handle to a file
and convert smb2_query_path_info() to use it. This will eliminate the need for a SMB2_Create when we already have an open handle that can be used. This will also prevent a oplock break in case the other handle holds a lease. Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
