[PATCH i-g-t] kms_atomic: drop unnecessary connector looping from plane_primary test

[Matt Roper <matthew.d.roper@intel.com>]

Local variable num_connectors is never initialized before being
auto-incremented in the loop.  If we wind up with a non-zero garbage
value, it will lead us to try to write to an out-of-bounds array index.
We should probably initialize it to zero before use.

However on closer inspection, the plane_primary test doesn't actually
wind up using the connector list or number of connectors, so just remove
the whole block of code; it was probably brought in by accident as part
of a copy-paste operation.
