Make the driver conditionally MPSAFE. MPSAFEty defaults to not-mpsafe

Browse source 
but can be enabled by setting hw.atm.hatmN.mpsafe in the kernel
environment to a non-zero value before loading the driver. When
the problems with network MPSAFEty have been sorted out this will
be removed and the driver will default to MPSAFE.
