[PATCH 2/5] ipr: Clear NO_ULEN_CHK bit when resource is a vset.

[Gabriel Krisman Bertazi <krisman@linux.vnet.ibm.com>]

According to the IPR specification, Inhibit Underlength Checking bit
must be disabled when sending commands to vsets.  Enabling this bit for
vset might cause SCSI commands to fail with an Illegal Request.
