Log Message:
Make scsipi framework MPSAFE.
Data structures are now protected by a per-adapter mutex at IPL_BIO
that is created by the scsibus or atapibus instance when the adapter
is configured.
The enable reference counter and the channel freeze counter which are
currently used by HBA code before the adapter is configured, are made
atomic.
The target drivers are now all tagged as D_MPSAFE.
Almost all HBA drivers still require the kernel lock to present,
so all callbacks into HBA code are still protected by kernel lock
unless the driver is tagged as SCSIPI_ADAPT_MPSAFE.
TODO: refactor sd and cd to use dksubr.
