staging: bcm2835-audio: Fix memory corruption
The previous commit (0adbfd46) fixed a memory leak but also freed a block in the success case, causing a stale pointer to be used with potentially fatal results. Only free the vchi_instance block in the case that vchi_connect fails; once connected, the instance is retained for subsequent connections. Simplifying the code by removing a bunch of gotos and returning errors directly.
