IB/ipath: remove some left over code

"ret" is always zero here after commit c4bce8032ef4 ('IB/ipath: Add new chip-specific functions to older chips, consistent init').

I just happened to spot this dead code when I was reviewing a different static checker warning:

drivers/infiniband/hw/ipath/ipath_verbs.c:2266 show_hca()
warn: bool is not less than zero.

It looks to me that this code returns 0 on success and 1 on failure so the warning is correct. This is very strange. The documentation doesn't say anything about what the return codes mean so it is all very puzzling.

Thanks for the patch!
