ipmi: use correct string length
gcc-8 reports
drivers/char/ipmi/ipmi_msghandler.c: In function
'panic_op_write_handler':
./include/linux/string.h:245:9: warning: '__builtin_strncpy' specified
bound 16 equals destination size [-Wstringop-truncation]
drivers/char/ipmi/ipmi_watchdog.c: In function 'set_param_str':
./include/linux/string.h:245:9: warning: '__builtin_strncpy' specified
bound 16 equals destination size [-Wstringop-truncation]
We need one less byte or call strlcpy() to make it a nul-terminated
string.
