[PATCH v2 01/10] compiler-context-analysis: Avoid unused parameter warning in _context_unsafe_alias()

[Ian Rogers <irogers@google.com>]

_context_unsafe_alias() does not use its parameter 'p', which triggers
-Wunused-parameter when building code that enables -Wextra (such as
tools/perf, tools/lib/perf, tools/lib/subcmd, and tools/lib/symbol).
Explicitly cast 'p' to void to silence the warning, matching
__assume_ctx_lock() and __assume_shared_ctx_lock().
