powerpc/iseries: Initialise on-stack completion

Browse source

get_viotape_info() declares a vio_waitevent on the stack, which
contains a completion, but never initialises the completion.

I have no idea how this ever worked, and on recent kernels it causes
an oops in handle_tape_event() when we access the non-initialised
completion.
