drm/amdkfd: Fix goto usage
Missed a spot in previous cleanup commit: Remove gotos that do not feature any common cleanup, and use gotos instead of repeating cleanup commands. According to kernel.org: "The goto statement comes in handy when a function exits from multiple locations and some common work such as cleanup has to be done. If there is no cleanup needed then just return directly."
