Perftest: Fix address cycling bug in local address increment logic

The increase_loc_addr() function manages circular buffer addressing.
One of the input argument is rcnt, which represents the number of
post_send/post_receive operations that were called per QP. Based on
rcnt, it internally calculates the local address for the next operation.
When setting up receive WQEs, this function is being called with the
index of the current operation instead of the amount that was already
called. This incorrect indexing caused the last WQE in the buffer to
incorrectly point to the first WQE's address in the QP.
This bug affects the cyclic address calculation used for cache-efficient
data placement. The fix ensures proper address cycling by passing the
correct index to the function.
