If a coprocessor encounters an error translating an address, the VAS
will cause an interrupt in the host.

NX issues an interrupt when sees fault on user space buffer. The
kernel processes the fault by updating CSB. This functionality is
same for both powerNV and pseries. So this patch moves these
functions to common vas-api.c and the actual functionality is not
changed.
