Namjae Jeon ef572ffa8e ksmbd: fix out of bounds read in smb2_sess_setup 
commit 98422bdd4cb3ca4d08844046f6507d7ec2c2b8d8 upstream.

ksmbd does not consider the case of that smb2 session setup is
in compound request. If this is the second payload of the compound,
OOB read issue occurs while processing the first payload in
the smb2_sess_setup().
