CIFS: Fix SMB2+ interim response processing for read requests

CIFS: Fix SMB2+ interim response processing for read requests

Orabug: 23330986

[ Upstream commit 6cc3b24235929b54acd5ecc987ef11a425bd209e ]

For interim responses we only need to parse a header and update
a number credits. Now it is done for all SMB2+ command except
SMB2_READ which is wrong. Fix this by adding such processing.
