powerpc/book3s: Print task info if we take a machine check in user mode
For an MCE (Machine Check Exception) that hits while in user mode
MSR(PR=1), print the task info to the console MCE error log. This may
help to identify an application that triggered the MCE.
After this patch the MCE console looks like:
Severe Machine check interrupt [Recovered]

Error type: SLB [Multihit]
