[PATCH 1/2] gpu: host1x: Fix an error handling path in 'host1x_probe()'

[Christophe JAILLET]

Add the missing 'host1x_bo_cache_destroy()' call in the error handling
path of the probe, as already done in the remove function.

In order to simplify the error handling, move the 'host1x_bo_cache_init()'
call after all the devm_ function.

Fixes: e3166698a8a0 ("drm/tegra: Implement buffer object cache")

Untested.
I hope that moving host1x_bo_cache_init() is just fine.
