[PATCH] media: mali-c55: Fix clock leak on reset deassert failure

[David Carlier]

__mali_c55_power_on() enables the clocks before deasserting the resets,
but bails out on a deassert failure without disabling them again. Both
callers treat a failed power-on as already cleaned up, so the clocks are
left enabled.

Disable them on the error path.
