scripts/gdb: de-reference per-CPU MCE interrupts

Browse Source 
The per-CPU MCE interrupts are looked up by reference and need to be
de-referenced before printing, otherwise we print the addresses of the
variables instead of their contents:

MCE: 18379471554386948492   Machine check exceptions
MCP: 18379471554386948488   Machine check polls

The corrected output looks like this instead now:

MCE:          0   Machine check exceptions
MCP:          1   Machine check polls
