[PATCH] staging: media: ipu7: fix MMU resource leak in ipu7_psys_init()

[Huihui Huang]

There is a memory leak in drivers/staging/media/ipu7/ipu7.c.

In ipu7_psys_init(), psys_adev->mmu is allocated by ipu7_mmu_init().
When ipu7_bus_add_device() fails, the function returns without
cleaning up the MMU resources.

Add the missing ipu7_mmu_cleanup() call on the error path to free
the MMU resources.
