The bit field rsvd1 in resp is not being initialized and garbage data
is being copied from the stack back to userspace via the ib_copy_to_udata
call. Fix this by setting the entire struct resp to zero; this will ensure
that further new bit fields in the future will be zero'd too.

V2: set entire struct resp to zero rather than the new field. Thanks to
    Jason Gunthorpe for suggesting this improved fix.

Applied to for-next, thanks

I amended it to remove the now redundant  = 0's.
