Adrian Hunter 8cddb0d96b perf/x86/intel/pt: Fix sampling using single range output 
commit ce0d998be9 upstream.

Deal with errata TGL052, ADL037 and RPL017 "Trace May Contain Incorrect
Data When Configured With Single Range Output Larger Than 4KB" by
disabling single range output whenever larger than 4KB.

Fixes: 670638477a ("perf/x86/intel/pt: Opportunistically use single range output mode")
