Bryan Venteicher 4dbc384845 Only set the barrier flag if the feature was negotiated
When the VirtIO barrier feature is not negotiated, the driver
must enforce the proper ordering for BIO_ORDERED BIOs. All the
in-flight BIOs must complete before starting the BIO, and the
ordered BIO must complete before subsequent BIOs can start.

Also fix a few whitespace nits.
