[PATCH 6.1.y v2 11/18] perf session: Don't write to memory pointed to a const pointer

[Shreenidhi Shedi <yesshedi@gmail.com>]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

commit f1321cce848c558fde4c0c6bcd5e53f3cefd3af2 upstream

Since it is freshly allocated just attribute it to a non-const pointer
and then change it via that pointer.

That way we avoid const-correctness warnings in recent glibc versions.
