6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steve French <stfrench@xxxxxxxxxxxxx>
commit 45be0882c5f91e1b92e645001dd1a53b3bd58c97 upstream.
Address static checker warning in cifs_ses_get_chan_index():
warn: variable dereferenced before check 'server'
To be consistent, and reduce risk, we should add another check
for null server pointer.
Fixes: 88675b22d34e ("cifs: do not search for channel if server is terminating")
