[PATCH v4 1/8] drm/v3d: Fix return if scheduler initialization fails

[Maíra Canal <mcanal@xxxxxxxxxx>]

If the scheduler initialization fails, GEM initialization must fail as
well. Therefore, if `v3d_sched_init()` fails, free the DMA memory
allocated and return the error value in `v3d_gem_init()`.
