shadow_copy2: Ignore VFS_OPEN_HOW_WITH_BACKUP_INTENT

Browse Source 
d1846452e96 vfs: Add VFS_OPEN_HOW_WITH_BACKUP_INTENT introduced
VFS_OPEN_HOW_WITH_BACKUP_INTENT for files opened with
FILE_OPEN_FOR_BACKUP_INTENT. shadow_copy2 refuses the open on a file if
any flage in how.resolve is set. Change the check in shadow_copy2 to
allow opening of files with VFS_OPEN_HOW_WITH_BACKUP_INTENT.
