Volker Lendecke d385058ce7 CVE-2022-3592 smbd: Slightly simplify filename_convert_dirfsp() 
subdir_of() calculates the share-relative rest for us, don't do the
strlen(connectpath) calculation twice. subdir_of() also checks that
the target properly ends on a directory. With just strncmp a symlink
to x->/aa/etc would qualify as in share /a, so a "get x/passwd" leads to a
pretty unfortunate result. This is the proper fix for bug 15207, so we
need to change the expected error code to OBJECT_PATH_NOT_FOUND
