[PATCH] adjust SG reserved size automatically

The block layer SG should have the identical behaviour as SCSI sg when
it comes to SG_SET_RESERVED_SIZE - allow caller to specify a large
amount, truncate to largest we support, and return that with
SG_GET_RESERVED_SIZE.  Currently we fail with -EINVAL if the value is
too large, I think the SCSI sg behaviour is more sane to use.  This
one-liner fixes it up, please apply for 2.6.8.
