Reinette Chatre 456824896d 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.
