s3: smbd: Tweak openat_pathref_dirfsp_nosymlink() to NULL out fsp->fsp_name after calling fd_close() on intermediate directories, rather than before.
vfs_virusfilter expects a non-NULL fsp->fsp_name to use for printing debugs
(it always indirects fsp->fsp_name). vfs_fruit also does the same, so would
also crash in fruit_close() with 'debug level = 10' and vfs_default:VFS_OPEN_HOW_RESOLVE_NO_SYMLINKS = no
set (we don't test with that which is why we haven't noticed
this before).
Remove knownfail.

selftest: Show vfs_virusscanner crashes when traversing a 2-level directory tree.
Modify check_infected_read() test to use a 2-level deep
directory.
We must have vfs_default:VFS_OPEN_HOW_RESOLVE_NO_SYMLINKS = no
set on the virusscanner share as otherwise the openat flag
shortcut defeats the test.
Add knownfail.
