Remove unused parameter form find_window_run_conditions()

Hi,

Reading find_window_run_conditions() the RangeTableEntry *rte parameter
is not being used by find_window_run_conditions() and
check_and_push_window_quals(). The attached patch remove this parameter
from both functions.

The 4be9024d573 also remove unused parameter for both functions and
after studying more these functions I founded that the RangeTableEntry
is not being used as well. I've checked the other parameters and all
seems to be used now.
