get_most_recent_post_of_user() should use get_blog_prefix()

[nacin]

Given the loop over multiple sites and the direct DB query against each post table, this function should probably be deprecated and killed.

That said, it currently uses {$wpdb->base_prefix}{$blog->userblog_id}, which won't work for the main site in 3.0+ multisite. That needs to change.

Use get_blog_prefix() in get_most_recent_post_of_user(). see #19891.

Use get_blog_prefix() in another MU function. see #19891.
