[PULL 38/53] target/i386: Correct the warning message of Intel PT |

From: Luwei Kang <luwei.kang@intel.com>
The CPUID level need to be set to 0x14 manually on old
machine-type if Intel PT is enabled in guest. E.g. the
CPUID[0].EAX(level)=7 and CPUID[7].EBX[25](intel-pt)=1 when the
Qemu with "-machine pc-i440fx-3.1 -cpu qemu64,+intel-pt" parameter.
This patch corrects the warning message of the previous
submission(ddc2fc9).
