[SCSI] ipr: move setting of the allow_restart flag for vsets and disks

A problem was found where the call to scsi_add_device() fails intermittently
for an adapter.  This is caused when __scsi_add_device() returns -ENODEV as
a result of not calling scsi_probe_and_add_lun() since the call to
scsi_host_scan_allowed() fails.  scsi_host_scan_allowed() fails because the
adapter state is set to SHOST_RECOVERY instead of SHOST_RUNNING. The state of
the adapter is being set to SHOST_RECOVERY by scsi_eh_scmd_add() during
error handling.

This problem is avoided by moving the setting of the allow_restart flag to
later in the device initialization sequence.  This prevents further error
handling if we get a NOT_READY response from a TUR command by causing
scsi_check_sense() to return SUCCESS.  Therefore, scsi_eh_scmd_add() will
not run and the adapter state will remain as SHOST_RUNNING.
