[PATCH i-g-t v4 3/5] lib/gem_engine_topology: Fix premature break from primary find loop

[Janusz Krzysztofik]

When looking for a primary counterpart of a render device, we try to open
each primary minor.  When one fails, we should continue rather then break,
since contiguity of minor numbers assigned to devices is not guaranteed.
