Android: fix incorrect parameter name comments

No change to behavior.

There were a few method calls in content layer where a comment is used
to indicate the parameter name, but the comment's param name doesn't
match the real parameter name. This CL changes the comment to match the
parameter name.

This is another errorprone compile warning.

Test: ninja system_webview_apk (warnings go away)
