[PATCH] ASoC: tpa6130a2: unmerge power enable error path from power disable path

[Nikita Yushchenko]

Code undo operations in power enable errror path explicitly, instead of
reusing power disable path and playing with return values there.

I doubt that copying 7 lines into error path is better than having a tiny
logic with return values, but still here it is.
