ksmbd: check if a mount point is crossed during path lookup
[ Upstream commit 2b57a4322b1b14348940744fdc02f9a86cbbdbeb ]
Since commit 74d7970febf7 ("ksmbd: fix racy issue from using ->d_parent and
->d_name"), ksmbd can not lookup cross mount points. If last component is
a cross mount point during path lookup, check if it is crossed to follow it
down. And allow path lookup to cross a mount point when a crossmnt
parameter is set to 'yes' in smb.conf.
