x86/resctrl: Use rdt_last_cmd_puts() where possible
The last_cmd_status sequence buffer contains user-visible messages (accessed via /sys/fs/resctrl/info/last_cmd_status) that detail any errors encountered while interacting with the resctrl filesystem. rdt_last_cmd_printf() and rdt_last_cmd_puts() are the two calls available to respectively print a string with format specifiers or a simple one (which contains no format specifiers) to the last_cmd_status buffer. A few occurrences exist where rdt_last_cmd_printf() is used to print a simple string. Doing so does not result in incorrect result or incorrect behavior, but rdt_last_cmd_puts() is the function intended to be used in these cases, as it is faster and it doesn't need to do the vsnprintf() formatting. Fix these occurrences to use rdt_last_cmd_puts() instead. While doing so, fix two typos that were recently introduced into two of these simple strings.
