Josh Poimboeuf d6d416f3b8 perf: Remove get_perf_callchain() init_nr argument

[ Upstream commit e649bcda25 ]

The 'init_nr' argument has double duty: it's used to initialize both the
number of contexts and the number of stack entries.  That's confusing
and the callers always pass zero anyway.  Hard code the zero.
