Adjust cifssb maximum read size
When session gets reconnected during mount then read size in super block fs context
gets set to zero and after negotiate, rsize is not modified which results in
incorrect read with requested bytes as zero. Fixes intermittent failure
of xfstest generic/240
Note that stable requires a different version of this patch which will be
sent to the stable mailing list.
