Dan Williams 0e7f074145 acpi, nfit: validate commands against the device type 
Fix occasions in acpi_nfit_ctl where we check the command type without
validating whether we are parsing dimm vs bus level commands. Where the
command numbers alias between dimms and bus we can make the wrong
assumption just checking the raw command number. For example, with a
simple nfit_test mock up of the clear-error command we trigger the
following:

    BUG: unable to handle kernel NULL pointer dereference at 0000000000000094
    IP: acpi_nfit_ctl+0x29b/0x930 [nfit]
