scripts/gdb: de-reference per-CPU MCE interrupts
commit 50f4d2ba26d5c3a4687ae0569be3bbf1c8f0cbed upstream.
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
