Too much escaping for pages when using Quick Edit

[nacin]

$post->post_title is escaped directly in the posts list table (for hierarchical post types), which then causes esc_textarea() in get_inline_data() to escape it one level too far.

The code is a vestige from [2029], when the_title() was used directly. This is no longer the case, leaving this code with no functional purpose.

(In [17682]) Remove vestige code, prevent over-escaping of post titles when using Quick Edit for hierarchical post types. fixes #17218.

(In [17704]) Remove vestige code, prevent over-escaping of post titles when using Quick Edit for hierarchical post types. fixes #17218 for the 3.1 branch.
