Subject: [PATCH][next] cifs: remove unused variable ses_selected

The variable ses_selected is being assigned values but it is never
being used. The variable is redundant and can be removed.

Cleans up clang scan build warning:
fs/cifs/smb2pdu.c:3810:19: warning: Although the value stored
to 'ses_selected' is used in the enclosing expression, the value is
never actually read from 'ses_selected' [deadcode.DeadStores]
