ksmbd: Fix smb2_set_info_file() kernel-doc comment

[ Upstream commit 4bfd9eed15e163969156e976c62db5ef423e5b0f ]

Fix argument list that the kdoc format and script verified in
smb2_set_info_file().

The warnings were found by running scripts/kernel-doc, which is
caused by using 'make W=1'.
fs/ksmbd/smb2pdu.c:5862: warning: Function parameter or member 'req' not
described in 'smb2_set_info_file'
fs/ksmbd/smb2pdu.c:5862: warning: Excess function parameter 'info_class'
description in 'smb2_set_info_file'
