If SC is not enabled, MGMT_OP_READ_LOCAL_OOB_DATA command does not
get the local oob extended data. And the length is smaller than
rp size. This patch removes the size checking logic, so will not
return the error for the normal case. We can handle the exception
case when the status is not MGMT_STATUS_SUCCESS.
