x86: PAT: fix ambiguous paranoia check in pat_init()
Starting with commit 8d4a4300 (x86: cleanup PAT cpu validation) the PAT CPU feature flag is not cleared anymore. Now the error message "PAT enabled, but CPU feature cleared" in pat_init() is misleading. Furthermore the current code does not check for existence of the PAT CPU feature flag if a CPU is whitelisted in validate_pat_support. This patch clears pat_wc_enabled if boot CPU has no PAT feature flag and adapts the paranoia check.
