i2c: Use trace_call__##name() at guarded tracepoint call sites
Replace trace_foo() with the new trace_call__foo() at sites already guarded by trace_foo_enabled(), avoiding a redundant static_branch_unlikely() re-evaluation inside the tracepoint. trace_call__foo() calls the tracepoint callbacks directly without utilizing the static branch again.
