Contrary to the claim in the commit message, there is recursive locking.
The meta stuff used by i965 does GL operations while the texture is
locked. If we don't allow recursive locks, it will deadlock. No, it's
not great, but it's the current state of affairs. Once we delete i965
in favor of crocus and any other users of meta, we can restore the above
patch. Until then, we need mtx_recursive.
