[ Upstream commit 1354d830cb8f9be966cc07fc61368af27ffb7c4a ]
In the unlikely event that pci_register_device() fails, we were tearing
down our PMU setup but not globals. This leaves a bunch of memory slabs
lying around.

Fixes: 32eb6bcfdda9 ("drm/i915: Make request allocation caches global")
[danvet: Fix conflicts against removal of the globals_flush
infrastructure.]
