ocrdma: missing break in switch statement.

[Dave Jones <davej@redhat.com>]

I've been going through the 'missing break' warnings in coverity, and there's a bunch
in infiniband. A lot look intentional, but this one can't be right.
We set a variable, and then immediately overwrite it.

instead of adding break spaghetti, just return the correct value.
