[PATCH 2/3] target/i386/cpu: Consolidate the use of warn_report_once()

[Zhao Liu <zhao1.liu@linux.intel.com>]

From: Zhao Liu <zhao1.liu@intel.com>

The difference between error_printf() and error_report() is the latter
may contain more information, such as the name of the program
("qemu-system-x86_64").

Thus its variant error_report_once() and warn_report()'s variant
warn_report_once() can be used here to print the information only once
without a static local variable "ht_warned".
