In an MP world, it doesn't hold that x86 requires no memory barriers.
This change should also fix panics due to out-of-sync data seen with
FreeBSD VMs on top of OpenStack and HBAs of type lsiLogic. [1]
While at it:
- Improve the granularity somewhat by distinguishing between read and
write memory barriers as well as refer to existing *mb(9) functions
instead of duplicating these [2], unless IO barriers are also used.
- Nuke the unused SYM_DRIVER_NAME macro.
