perf auxtrace ptt: Record whether an auxtrace mmap is needed 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7HI80


CVE: NA

----------------------------------------------------------------------

Add a flag needs_auxtrace_mmap to record whether an auxtrace mmap is
needed, in preparation for correctly determining whether or not an
auxtrace mmap is needed.

The change was added in the mainline [1], but it was deleted
when upstream openEuler for fixes build error. openEuler OLK-5.10
now has merge evsel->needs_auxtrace_mmap. Therefore, backport this
modification to OpenEuler OLK-5.10.

HiSilicon PCIe Tune and Trace device driver")
