Fix TRACE_IPIIRQ_FORMAT string format width overflow scan issue
cppcheck detected a potential buffer overflow with a %s scanf width format
specifier being larger than the destination buffer. Reduce the scan size to
match the expected buffer size.
Fixes error:
[idlestat.c:974]: (error) Width 32 given in format string (no. 2) is larger
than destination buffer 'irqname[17]', use %16s to prevent overflowing it.
