[SCSI] fusion - fix pci express bug
The fix is to write 'MPI_HIM_DIM' to the Host Interrupt Mask register, when enabling interrupts. Instead of the tilde of MPI_HIM_RIM. Apparently writing '1's to some of the reserved bits was causing all the bits to go to `1`, which effectly disabled all interrupts.
