Disable recursion on the general UMA lock now that startup_alloc() no longer uses it. Eliminate the variable uma_boot_free. It serves no purpose. Note: This change eliminates a lock-order reversal between a system map mutex and the UMA lock. See http://sources.zabbadoz.net/freebsd/lor.html#109 for details.
