[PATCH] IB/mthca: Move mthca_is_memfree checks 

Make mthca_table_put() and mthca_table_put_range() NOPs if the device is not
mem-free, so that we don't have to have "if (mthca_is_memfree())" tests in the
callers of these functions.  This makes our code more readable and
maintainable, and saves a couple dozen bytes of text in ib_mthca.ko as well.
