smb/server: use end_removing_noperm for for target of smb2_create_link()

Browse source

Sometimes smb2_create_link() needs to remove the target before creating
the link.
It uses ksmbd_vfs_kern_locked(), and is the only user of that interface.

To match the new naming, that function is changed to
ksmbd_vfs_kern_start_removing(), and related functions or flags are also
renamed.

The lock actually happens in ksmbd_vfs_path_lookup() and that is changed
to use start_removing_noperm() - permission to perform lookup in the
parent was already checked in vfs_path_parent_lookup().
