ksmbd: Implements sess->ksmbd_chann_list as xarray

Browse source

[ Upstream commit 1d9c417211 ]

For some ops on channel:
1. lookup_chann_list(), possibly on high frequency.
2. ksmbd_chann_del().

Connection is used as indexing key to lookup channel, in that case,
linear search based on list may suffer a bit for performance.

Implements sess->ksmbd_chann_list as xarray.
