s3: smbd: In call_trans2qfilepathinfo(), TRANSACT2_QPATHINFO on a named stream case, use helper function vfs_stat().
This isn't a change in behavior, even though the
old comment says: "Always do lstat for UNIX calls".
A previous commit enforces POSIX pathname negotiation
before allowing UNIX info levels to be processed here,
so we can guarantee that SMB_FILENAME_POSIX_PATH is set
on smb_fname if we're allowing a UNIX info level.
