[PATCH][next] RDMA/mlx5: remove redundant check on err on return expression

[Colin Ian King]

Currently all paths that set err and then check it for an error
perform immediate returns, hence err always zero at the end of
the function _mlx5r_umr_zap_mkey.  The return expression
err ? err : nblocks has a redundant check on the err since err
is always zero, so just return nblocks instead.
