ksmbd: add chann_lock to protect ksmbd_chann_list xarray
commit 4f3a06cc57976cafa8c6f716646be6c79a99e485 upstream.
ksmbd_chann_list xarray lacks synchronization, allowing use-after-free in
multi-channel sessions (between lookup_chann_list() and ksmbd_chann_del).
Adds rw_semaphore chann_lock to struct ksmbd_session and protects
all xa_load/xa_store/xa_erase accesses.
